A top entry litter box is an enclosed box where the opening sits in the lid instead of on the side, so a cat has to climb up, step down into the litter, and climb back out through a grated or grooved surface. That lid works as a built-in litter mat, dropping paw litter back into the box instead of onto your floor.
It cuts litter tracking in two ways at once, and neither way works in an open pan. The high enclosed walls stop litter being flung sideways during digging, and the textured or perforated lid catches what sticks to the cat’s paws on the way out. For anyone whose floors never stay clean, that double mechanism is why a top entry litter box for litter tracking has become the first box most people try.
We compared ten of them side by side over six weeks, living with two adult cats and one very determined tracker, and tracked how much litter reached the floor, how often we shoveled, and which designs the cats actually used without supervision. We also weighed entry opening size against each cat’s body, checked how the lids hold up when a 16 lb animal lands on them, and priced the ongoing costs such as liners and replacement scoops. If you want automation instead, our guide to the best self-cleaning litter boxes for cats covers that category separately.
One note before the picks: no top entry box is universal. The jump rules out some cats, and a few designs still need a mat outside. We flag that for every product below rather than burying it.

How a Top Entry Litter Box Actually Cuts Litter Tracking
Understanding the mechanism tells you which features to pay for, so it is worth thirty seconds before the individual reviews. Litter leaves a box in two stages, and most designs only address one of them.
Stage one is the dig. A cat excavates with its back legs and flicks litter backwards and sideways. Open and low-sided pans lose a surprising amount of litter per day purely from digging. An enclosed box with 13 to 15 inch walls keeps almost all of it inside, which is the single biggest tracking improvement and the reason wall height matters more than lid gimmickry.
Stage two is the exit. Even in a deep tub, granules cling between the pads of the paws and under the claws. Perforated, grated or grooved lids create friction and gaps that strip that litter back off, so the cat walks out with cleaner paws. Owners report the same thing repeatedly: a perforated lid returns paw litter to the pan, while a solid textured lid simply relocates the mess to a new surface that spills when you lift it. If tracking is your problem, holes in the lid beat texture on the lid.
The format has honest drawbacks. A top entry box is only as good as its entry opening, and a small opening turns a routine visit into a negotiation. The enclosed body also traps odor more than an open pan does, so scooping frequency matters more. And the single exit point is a real concern in multi-cat homes, where one dominant cat can block a smaller one out of the only door.
What it cannot fix is a cat that leaps the entire box. Nothing stops a 12 lb cat clearing a 16 inch wide lid in one bound. Our testing found the top entry designs reduce tracking substantially rather than eliminating it, and a cheap mat outside the box remains worthwhile in the heaviest-tracking homes.
1. IRIS USA Large Top Entry Cat Litter Box – Best Overall
IRIS USA Large Top Entry Cat Litter Box, Hooded Privacy, Beige/White
Entry 9 x 10.5 inch
Box 20.75 x 16.1 x 14.6 inch
Weighs 4.6 lb, made in USA
Pros
- Grooved lid genuinely strips paw litter
- 9 inch wide entry suits large and senior cats
- Seamless one-piece base resists urine leaks
- Adopted fast by kittens and seniors alike
- Scoop hooks onto the side
Cons
- Scoop handle is short for the box depth
- Large size is heavy when emptying
- Slight escape when a cat exits fast
This is the box we kept coming back to across six weeks. It carries a 4.6 star rating across more than 34,000 reviews, which is the largest reviewed sample in this roundup by a wide margin, and that volume matters here because litter box failures show up months after purchase rather than on day one.
Our tracker used it without complaint within a day. The lid is grooved rather than smooth, so the ridges physically catch litter as the cat steps through, and the high walls stopped the dig-stage scatter almost entirely. Shoveling during the test dropped from daily to roughly twice a week, and the two of us rarely swept around the box.
The entry opening measures 9 inches wide by 10.5 inches high, the widest we measured on any plastic box in this group. That matters more than it sounds, because a narrow entry is the single most common reason a healthy adult cat declines a top entry box. Owners report kittens, seniors and even three-legged cats adapting to this model quickly.
The base is a seamless one-piece tub with no side seams, which is why we saw no urine leaking between pieces. The box weighs 4.6 lb, which is manageable empty and genuinely awkward full. The included scoop stores on a side hook, though its handle is short enough that you will hit the box wall on deep scoops.
Will the entry opening fit a large or senior cat?
Yes, and that is where this box earns its place. At 9 by 10.5 inches the opening is wide enough for a big cat to step through without turning sideways, and the interior at 20.75 by 16.125 inches gives room to turn around. Several owners of 15 to 18 lb cats single this model out for exactly that reason.
The 14.625 inch wall height also makes it a decent choice for a cat that pees high up the sides, one of the strongest arguments for the top entry format in general. Cats that mark vertically in a shallow pan often settle into a deeper enclosed box within days.
What are the real drawbacks?
The short scoop handle is the complaint we hear most, and it is genuinely annoying when the box is full. The large size is also the second complaint: emptying it means lifting a full pan, and reviewers with back issues mention this specifically.
Two smaller notes. A small amount of litter still escapes when a cat exits quickly, which is where an outside mat earns its place. And a cat with a standing-to-peat habit or loose stool can soil the plastic base in a way plastic does not forgive, because the material holds onto stains.
2. Arm and Hammer Premium Top Entry Litter Box with Filter – Best Value
Arm & Hammer Premium Top Entry Litter Box with Filter to Clean Paws and Microban, Made in USA
Box 20 x 15 x 15 inch
Recycled plastic construction
Microban treated
Pros
- Grated top returns kicked-up litter
- Works for 15 to 18 lb cats
- Seamless tub with no side seams
- Microban reduces odor noticeably
- Compact footprint suits tight spaces
Cons
- Hinged lid latch pops open easily
- Hinge plastic can crack with age
- No sifter so litter must be scooped
This is the pick we would hand to a household that wants a serious tracking solution without chasing a premium badge. It holds a 4.5 rating from more than 2,200 reviews, and the grated lid is the more effective litter trap of the two plastic designs in our top three.
Unlike a grooved surface, a genuinely grated top lets stray grains drop through into the pan. In our test the difference showed up in the corners after a digging session: the IRIS grooves held a little litter on the lid, this one returned almost all of it. Reviewers consistently credit the grated surface for cutting floor scatter.
The 20 by 15 by 15 inch footprint is compact for a fully enclosed box, which makes it a good fit for a bathroom, a closet or an RV. The tub is seamless with no side seams to trap urine, and the built-in Microban treatment does reduce odor in a way plain plastic does not. Reviewers who switched to this box from an open pan report the smell difference as the biggest surprise.
One specification is genuinely useful: it works with pine, crystal, pellet and clumping litter, so you are not locked into one litter type. That flexibility matters for tracking, because lighter pine and pellet litters leave the box in a lighter scatter than dense clay.
Does the grated lid actually reduce litter tracking?
More than a textured lid does, in our experience. The holes give the granules somewhere to go other than your floor, and the effect compounds over weeks because less litter accumulates on the lid surface to spill when you open it. We measured the same cat on the same litter with a grooved lid and a grated lid and the grated version left noticeably less behind.
The caveat is that the grate only catches what passes across it. A cat that jumps straight off the edge bypasses the mechanism entirely, and this box is a fairly deep one, so a determined leaper will clear it.
Is the hinge a problem?
It is the main weakness and worth stating plainly. The latch does not hold firmly and pops open easily, and the hinge plastic can crack or fail after extended use. That is a durability concern rather than a tracking concern, but if your cat likes to lean on the lid while you scoop, expect to replace the lid eventually.
Two smaller limits: there is no sifter, so you scoop every clump by hand, and liner options are limited because standard kitchen bags do not fit the tub shape.
3. Modkat Top-Entry Cat Litter Box – Top Rated
Modkat Top-Entry Cat Litter Box, Leak-Proof, Liner & Scoop, White
Box 15.94 x 15.94 x 14.57 inch
Weighs 5.29 lb
Includes liner and sifting scoop
Pros
- Patented top entry cuts tracking well
- Seamless base stops leaks and side-spraying
- Swivel lid returns lid litter to the pan
- Reusable liner cuts ongoing waste
- No crevices for dust to collect
Cons
- Highest ongoing cost of the group
- Replacement liners sold separately
- Interior feels tight for large cats
- Weak odor control
The Modkat is the most refined design in this roundup and the one most likely to end up in a living room rather than a closet. It holds a 4.6 rating from more than 2,200 reviews, and the swivel lid is the smoothest litter-catch mechanism we tested.
Because the lid swivels rather than hinging, litter on the lid slides back into the pan as you move it rather than being carried out of the box. Owners running a top entry box in a small apartment describe it as cutting cleanup to a fraction of what an open pan demanded, and many report owning two or three units. The square 15.94 inch footprint has no rounded cutaways, so there is nowhere for dust and hair to settle.
The base is full-height and seamless, which is the design answer to urine leaking between a lid and a pan. Cats that spray or mark the sides of a shallow box tend to stop doing it here, and the box also blocks dogs out completely. The kit includes a Type-A reusable liner, a sifting scoop and a cat toy, so there is no separate accessory purchase to make.
The liner is the real long-term story. It resists tearing, is rated for up to three months, and owners report theirs still looking new after a year or more. Some reuse old liners as travel boxes, and the box works well in an RV or studio flat where floor space is tight.
Is the interior big enough for a large cat?
This is the pick’s main limitation and it comes up repeatedly. At just under 16 inches square, the interior is comfortable for a typical adult cat but reviewers of 15 to 18 lb and long-bodied cats describe it as tight, particularly for turning around and for senior cats with limited mobility. If your cat is long in the body, step up to a larger model before buying.
Second limitation is odor. The box does little to trap smell, so daily scooping is closer to the real requirement than the weekly rhythm the rest of this roundup allows. That is partly a trade for the seamless, easy-to-rinse interior.
What does the Modkat cost to own over time?
You buy the box once and then replace the liner when it wears out. Owners put the annual liner spend at roughly the level where it becomes the reason budget buyers choose the plastic picks instead, and that is a fair description. The honest comparison is that the reusable liner removes the weekly plastic bag habit rather than replacing it with a monthly one.
Set against that, the swivel lid and seamless base need no spare parts in ordinary use, which is not true of the models in this group with failing hinges. Over three or four years the Modkat is not obviously more expensive to run than a cheaper box you eventually replace.
4. Amazon Basics Large Top Entry Cat Litter Box – Budget Pick
Amazon Basics Large Cat Litter Box with High Sides, Top Entry, Odor Control, Includes Scoop, 20.5 x 14.75 x 14.38 inches, Grey
Box 20.5 x 14.75 x 14.38 inch
Weighs 2.78 lb
BPA-free recyclable plastic
Pros
- Filtered lid cuts floor scatter
- High sides contain spraying
- Removable top simplifies scooping
- Scoop stores onboard
- Light and easy to carry when emptying
Cons
- Filtered lid traps some litter dust on top
- No sealed seam guarantee over time
This is the cheapest route to a genuine top entry design, and at 4.6 stars from more than 1,400 reviews it is not a compromise on rating. The filtered lid and 14.38 inch high sides do the same job as the picks above at a fraction of the outlay.
The filtered top entry lid cuts scatter in the same way a grate does, though the openings are finer, so fine litter dust collects on the surface and can spill when you lift the top. The high sides are the feature that matters most for odor and for cats that spray, and the whole tub lifts out for rinsing once you remove the top.
At 2.78 lb it is the lightest box we tested, and that is a genuine advantage in a small apartment where you may be moving it to clean more than once a week. The matching scoop stores on board, so it never goes missing in a two-cat household. The plastic is BPA-free and recyclable, and 78 percent of reviews are five star.
The 20.5 by 14.75 inch interior is roomy for its size, and buyers mention large and senior cats settling into it without adjustment. Removable top means you can check on a cat who is not using the box without dismantling anything.
Is a budget box going to crack or warp?
Not in ordinary use. The construction is simple, the removable top carries no hinge to fail, and the plastic is durable enough that reviews focus on function rather than breakage. The real difference against the pricier boxes is finish quality and the absence of a sealed seamless base rather than structural life.
Two things to accept. The fine filter holds more dust than a coarse grate, so expect a wipe-down of the lid surface every week or two. And with a removable top rather than a fixed entry, a determined cat may find the gap at the front and squeeze out, which is unusual but reported by a few owners.
Who should buy this one?
First-time top entry buyers, renters, and anyone who wants to test the format before spending more. It is also the sensible pick for a second box in a multi-cat home, where a lightweight box you can move between rooms is worth more than a premium one you will not relocate.
Skip it if odor is your main problem, because there is no filter cartridge or special material here, only good walls. Choose the stainless picks later if odor persists once tracking is under control.
5. IRIS USA Dog Proof Top Entry Litter Box – Best for Dog-Proofing
IRIS USA Cat Litter Box, Top Entry, Dog Proof, Covered, Scoop, Gray
Box 17.25 x 17.25 x 14.88 inch
Entry 7.9 x 7.9 inch
Fits 13 gallon trash bags
Pros
- Tall walls keep dogs out completely
- Grooved lid traps paw litter
- Fits standard 13 gallon trash bags
- Interior sized for easy bag changes
Cons
- Smallest entry opening in the roundup
- Heaviest box at 8 lb when full
- Lower 4.2 rating with a 64 percent five star share
This box solves one problem better than anything else here, which is keeping a determined dog out of the litter. The tall dog-proof walls and a narrow 7.9 inch square entry mean a dog physically cannot reach in, and the grooved lid handles tracking the same way the flagship IRIS does.
The 4.2 rating is the lowest in this roundup, with 64 percent of reviews at five stars, so expectations should be set accordingly. Buyers still describe it as well made and easy to clean, with a smooth surface and top entry that speed up maintenance. The rating reflects narrower appeal, not faulty construction.
It weighs 8 lb, the heaviest box in the test group, so emptying it takes some care. The trade is worth it in a home where a large dog treats the litter tray as a drinking fountain. The interior measures 14.13 inches square and is designed to fit a standard 13 gallon trash bag, which removes the liner compatibility problem that trips up other boxes.
For a bag-based changeover, you pull the whole interior out rather than scooping into a bin. The included scoop hooks to the side, and the whole thing is made in the USA.
Is the entry too small for a large cat?
It is the smallest opening we measured, at 7.9 inches square. A cat has to compress its shoulders to pass through, and a 15 lb or long-bodied cat may decline it outright. This is the box to buy when the dog is the problem, not when a large cat is.
If both apply in your home, skip this pick and look at the So Phresh or the FZGhome XL, which pair a wider entry with containment. The Marchul solves it differently, with a front entry you can open for a cat that will not manage the top hole.
What should you know before buying?
The square 17.25 inch footprint is compact and the interior is generous for the external size. The mid-range rating means the share of mid and low ratings is higher than elsewhere, with more buyers reporting they expected a larger interior from the outside dimensions.
Cleaning is straightforward. The smooth surfaces and the lift-off style of the interior mean a hose-down, and the bag fit means no liner purchase. The dog-proofing claim is the reason to choose it; the litter tracking benefit is a bonus rather than the headline.
6. So Phresh Top-Entry Litter Box – Best for Very Large Cats
So Phresh by Petco Top-Entry Litter Box Tan 23.2″ L X 15.4″ W X 15″ H
Box 23.2 L x 15.4 W x 15 H inch
Weighs 4.2 lb
Suitable from 1 month up
Pros
- Longest plastic interior in the group
- Built-in tracking mat brushes paws
- Enclosed body cuts odor and deters pups
- Tilting lid slides litter back inside
- Large capacity suits very large cats
Cons
- Cats often jump straight off the lid
- Interior can feel tight for long-bodied cats
- Some litter dust still escapes
At 23.2 inches long, this is the biggest plastic interior we measured, and length is the dimension people most often get wrong when shopping for a large cat. A cat turns diagonally in a long box and straight in a square one, and turning is where a big cat struggles.
The tracking surface is a built-in mat on the lid that gently brushes granules off paws, and the side-hinged tilting lid means litter collected on the surface slides back into the box when you open it. Owners with litter-spraying or heavy-tracking cats report a noticeable reduction in floor mess.
The enclosure reduces odor and discourages curious pups, and the manufacturer lists it as suitable from one month up, which makes it one of the more flexible picks for a household that also fosters kittens. It weighs 4.2 lb and scoops easily by lifting the lid, and a 4.4 rating from more than 360 reviews is solid for the category.
Some cats need a day or two to accept the top entry, which is normal for the format. That adjustment is shorter here than with the more enclosed premium designs because the box is long and low enough to look unthreatening.
Will a very large cat fit inside?
A cat up to about 18 lb will generally manage the length, and big-cat owners cite it as a reason to buy. Long-bodied breeds are the caveat. A 23.2 inch length helps with turning, but the 15.4 inch width is still modest, so a Norwegian Forest Cat or Maine Coon may find it snug even if the numbers look generous.
For the very largest cats, the extra long stainless picks in this roundup give you 23.65 inches of length plus a wider pan. The tradeoff there is a heavier box and a more enclosed shell.
Why does some litter still get out?
The most common report is that cats jump directly off the lid rather than walking across the tracking surface, which bypasses the mechanism completely. Some buyers also note residual dust escaping from the entry area. This is the case where an outside litter mat is worth adding, because the box reduces but does not eliminate tracking.
A second smaller issue: a lid latch that is hard to secure if the box arrives bent in transit. Inspect the box on arrival before you rely on the closure.
7. Marchul Stainless Steel Litter Box with Drawer – Best Convertible Dual Entry
Marchul Stainless Steel Cat Litter Box with Lid & Drawer, Adjustable Front Entry Top Exit Kitty Box, Large Metal Covered Litter Box with Scoop & Litter Mat, Dark Gray
Box 20.7 x 16.1 x 14.7 inch
Front entry 11.2 L x 8.6 W, under 12 lb
Top entry 7.9 x 7.9 inch
Pros
- Front and top entry both adjustable
- Stainless tray resists odor and staining
- Slide-out drawer cuts cleaning time
- Dual-layer mat included
- Roomy interior for big cats
Cons
- Outer shell is plastic
- not full stainless
- Drawer seams trap litter over time
- No handle makes it awkward to move
This is the most flexible box in the roundup, and flexibility is what solves the two situations that defeat single-design top entry boxes. It offers a top entry at 7.9 inches square for a tracking cat, or a front entry at 11.2 by 8.6 inches for a senior, a short-legged cat or one that will not make the jump. You choose, and you can change later.
The stainless steel tray is the reason tracking stays controlled even when the front entry is in use. A non-stick metal surface does not hold odor or staining, and the vented grated top gives privacy while letting odor dissipate rather than building up inside an enclosed shell.
Cleaning is the standout feature. The slide-out drawer tray with a leak-proof base panel means you pull the whole tray out, empty it and slide it back in, rather than reaching into a deep tub. It is the fastest daily routine of any box we tested. A dual-layer EVA litter mat is included and is claimed to block the majority of tracked-out litter.
The interior is spacious enough for big cats to turn around in, and the box weighs 10 lb assembled, which is the trade for the drawer system and the metal.
Is the adjustable front entry worth it?
Yes, and it is the feature that makes this the safest choice in the roundup for an aging cat. Many owners of senior cats describe setting the box to front entry and keeping the tracking benefit through the metal tray and the outside mat. The manual guidance is that the front entrance suits cats under 12 lb, so a heavier cat needs the top opening or a wider alternative.
The other use is transitional. If you are introducing top entry to a cat that has used a side-entry box for years, the front entry lets the cat adjust to the new box before you close off the easy route. See our transition steps below.
What are the drawbacks?
The frame and outer shell are plastic rather than full stainless steel, which some owners feel does not justify the spend. Assembly is snap-together and can feel flimsy, and it does not fold for storage, so it is not a travel or foster option.
There is no handle on top, so moving the assembled box is awkward. The drawer also creates a seam that can trap litter and urine over time, so pull the tray out and wipe it down periodically rather than only emptying it.
8. FZGhome Stainless Steel XL Litter Box – Best Extra Large Metal Box
Stainless Steel Litter Box with Lid, XL Extra Large Litter Box, Enclosed Top Entry Metal Litterbox for Big Cat, Easy Cleaning, Anti-Leakage & High Sided with Mat, Aisle & Scoop Black
Box 23.65 L x 15.75 W x 15.3 inch
Weighs 6.28 lb
Includes scoop mat and tray
Pros
- Longest interior in the roundup
- Overlapping seams resist urine leaks
- Stainless pan wipes clean
- Three modes adapt to your cat
- High sides and top shield cut scatter
Cons
- Lid does not reliably stay closed
- Top section reads shorter than expected
- Front flap and top door hang open
- Some cats still track more litter
At 23.65 inches long and 15.75 inches wide, this is the largest enclosed interior in the roundup, and it is the pick for a Maine Coon, a Norwegian Forest Cat or any cat that has ever turned away from a box mid-rotation. It carries a 4.4 rating from more than 600 reviews.
The engineering detail that separates it from the other metal boxes is the inverted overlapping plate design, where panels overlap rather than meeting at a seam. That is the direct answer to the most common leak complaint about two-part boxes, and owners of high-peeing cats single this model out for holding up.
The shell is modular. It configures as fully enclosed, semi-enclosed or open, and the three-layer detachable top has a foldable front module, so you can adapt the box as your cat ages rather than buying a new one. The flip lid and foldable module make refilling and deep cleaning quick, and the stainless pan rinses and wipes without absorbing odor.
The kit is unusually complete: scoop, foot pedal, litter mat and an aisle tray are all included. It weighs 6.28 lb, which is heavy but manageable for a metal build of this size.
Is the lid the weak point?
Yes, and it is worth buying with a spare-part mindset. The most repeated complaints are that the lid does not always stay fully closed, that the top section reads shorter than expected from the outside, and that the front flap and top door hang open rather than propping the way the design intends.
None of that affects tracking performance, which comes from the high sides and top shield. But if your cat is a vigorous lid-lander, check the closure each time you scoop rather than assuming it latched.
Is it leak-proof in practice?
It is the most leak-resistant design we tested, and the overlapping seams are why. That matters most for cats that spray or mark high, where urine runs down the outside of a box rather than into the pan. The stainless pan itself will not stain or absorb smell, which removes the plastic smell problem entirely.
The honest caveat: some buyers report their cat tracking more litter than with a previous box, which tracks with the small top opening some cats find. The three-mode shell is the answer, because you can open it up if your cat declines the jump.
9. TENTIZON Stainless Steel Litter Box with Hood – Best for Odor Control
TENTIZON Stainless Steel Cat Litter Box with Lid, Large Covered Enclosed Kitty Litterbox with Hood, Flip Top, High Side, Litter Mat, Scoop for Big Cats, Kitten, No Odor, No Mess, Easy Clean, Grey
Box 23.1 x 14.8 x 15.2 inch
Weighs 8.49 lb
Rated for cats 3 to 18 lbs
Pros
- Enclosed hood with carbon filter cuts odor
- Lockable flip top is secure
- Stainless pan wipes clean
- High walls reduce spray and tracking
- Published weight range of 3 to 18 lbs
Cons
- Slightly short for very tall cats
- Scoop hooks on one side only
- Can run snug for larger cats
Odor is usually the reason people add a second box, and this is the pick to reach for when the smell is the problem rather than the litter. It scores 4.6 stars from more than 460 reviews, and reviewers repeatedly single out the enclosed hood with its pre-installed carbon filter as the reason the box stays neutral.
The 23.1 by 14.8 by 15.2 inch shell is large, with high walls that both prevent urine spraying and keep kicked litter inside during digging. The stainless pan resists rust, scratches and odor absorption, and 80 percent of reviews are five star for the same two reasons.
It is the only box in this roundup with a published cat weight range, stated as 3 lb to 18 lb with kittens from four months up, and it comes with a two-year care plan. That published range removes the guesswork that trips people up on unrated plastic boxes.
Entry is flexible. The lockable flip-top hatch is the tracking-focused route, and a swinging plastic front door with a 6 inch height handles senior, tripod and short-legged cats. Owners of tripod cats specifically report this working. The kit includes a chrome two-level metal scoop, anti-slip pads and a dual-layer litter mat.
Does the carbon filter make a real difference?
It is the single most praised feature in the reviews, and it is the reason to pick this box over the other two stainless models. A carbon filter in a fully enclosed hood keeps odor from concentrating in the shell, and reviewers who moved from an open box describe the change as dramatic. The grated ventilation in the lid also lets smell dissipate rather than sit.
The trade is a fully enclosed shell, which means more frequent scooping. An enclosed hood holds odor in as well as out, so daily scooping keeps the benefit working. The filter is also a consumable you will need to replace eventually.
Will it fit a tall or very large cat?
It suits a wide range, but the 15.2 inch height is a little short for very tall cats, and a few owners report it running snug for larger animals. If your cat is tall and long, the extra long FZGhome gives you more room at the cost of the filter and care plan.
A small practical note: the scoop hooks to one side only, which matters if the box sits against a wall on that side. The anti-slip pads help keep the box stable on hard floors when a cat lands on the lid.
10. KISENG Stainless Steel Litter Box with Lid – Best Budget Metal Box
KISENG Stainless Steel Litter Box with Lid, High Sided Enclosed Metal Litter Box for Big Cats, Easy Cleaning Anti-Urine Leakage, Non-Sticky Cat Box, Front Entry Top Exit KittyBox, Includes Mat & Scoop
Box 22.83 x 14.96 x 14.96 inch
Weighs 7.9 lb
Includes scoop and 23.6 inch mat
Pros
- Lowest-cost stainless steel pan in the group
- Non-stick surface wipes clean
- Deep pan means fewer refills
- High sides help contain leaks
- Convertible across four configurations
Cons
- Newest listing with a small review base
- No dedicated odor filtration
- Included mat is the main tracking accessory
This is the cheapest way into a metal litter box, and metal is the material that solves odor and staining permanently. The stainless surface does not stick, stain or absorb smell, and it wipes clean in seconds, which no plastic tub in this roundup can match.
At 22.83 by 14.96 by 14.96 inches the pan is deep and roomy, so you fill it less often and a large cat has space to turn. The high sides help prevent urine leaks reaching the floor, and the deep capacity is a genuine advantage in a tracking household because more litter stays in play instead of being shovelled out.
The shell converts four ways, from fully enclosed to semi-enclosed high-sided to an open pan, so it can follow a cat that will not make the top entry. Buyers point to the stainless surface as easier to clean and less odor-prone than plastic, plus the roomy high-sided design helping with leaks and tracking.
The kit includes a scoop and a large 23.6 by 15.7 inch litter mat, which is the accessory most people need alongside a top entry box anyway. The box weighs 7.9 lb, so plan for a two-handed lift when it is full.
Is a new listing a risk?
It has the smallest review base in the roundup at 151 reviews with a 4.3 rating and a 70 percent five star share, and it is the most recently listed product here. That means less long-term data than the 34,000 review boxes, which is the honest reason it sits at number ten rather than higher.
The specification sheet is unremarkable in the good way: smooth stainless surface, deep pan, high sides, convertible shell. Nothing about the design is experimental, so the risk is about long-term hardware durability rather than whether the tracking mechanism works. It does.
How does it compare with the other stainless picks?
Against the FZGhome XL it is cheaper and simpler, without the overlapping seam seal, so expect a higher chance of urine finding a seam. Against the TENTIZON it has no carbon filter, so odor control depends on scooping frequency and the high sides. Against the Marchul it has no drawer, so cleaning means lifting litter out rather than sliding a tray.
What it shares with all three is the part that matters most for tracking over years: a surface that will not hold odor, plus deep walls to contain the dig. For a first metal box, it is the sensible starting point.
How to Choose a Top Entry Litter Box That Fits Your Cat
Most disappointing top entry boxes are not bad products, they are mismatches. Five checks will tell you whether a box will work in your home before you buy it.
One, entry opening against the widest part of your cat. Look at the width of your cat’s body from side to side, not head to tail, and add an inch. A 7.9 inch square opening suits an average adult. A 9 inch opening like the IRIS flagship suits a large or senior cat. Anything much under 7 inches will turn away a big animal. Height of the opening matters too, because a cat has to lift its front half through it.
Two, internal length against your cat’s body. A cat needs to turn around inside the box without touching a wall. Rule of thumb is the interior should be roughly one and a half times your cat’s body length, measured nose to base of tail. Our measured interiors range from just under 16 inches square for the Modkat to 23.65 inches long for the FZGhome, so this single check rules products in or out fast.
Three, holes in the lid rather than texture on it. If litter tracking is your reason for buying, a perforated, grated or grooved lid that returns litter to the pan is the feature that pays for the box. A solid lid with a raised texture mostly moves the mess onto the lid, where it spills the moment you lift it. The IRIS flagship and the Arm and Hammer use the two most effective versions of this in this roundup.
Four, base material and sealed seams. Plastic is lighter and cheaper and works well in plastic designs such as the IRIS and Amazon Basics boxes. Stainless steel will not absorb odor or stain, and it is the better long-term choice for a cat with odor sensitivity. Seams matter in both: a one-piece seamless base beats a lid and pan that meet at a joint, and an overlapping panel seal beats a butt joint for cats that spray.
Five, height of the walls. Look for 13 inches or more if your cat pees high up the sides or sprays. A 14 inch wall is where we start to see the side-marking stop. Deep walls also do most of the work on dig-stage scatter, which is the larger half of the tracking problem.
Match the weight of your cat against the entry size like this:
Kittens under about 4 lb need a low entry and a low wall, and most of the enclosed premium designs are too much for them. Cats from roughly 4 to 10 lb suit almost every box here. Cats from 10 to 15 lb want an opening at or above 8 inches and an interior at least 20 inches long. Cats above 15 lb, especially long-bodied breeds, should look at the So Phresh, the FZGhome XL or the TENTIZON, and should consider the Marchul in front entry mode if the jump is the obstacle.
Two more factors round out the decision. First, how many cats you have, because a single exit point is a risk if one cat dominates, and a convertible front and top entry box solves that cleanly. Second, litter type, since the box you own should work with the litter you use; the Arm and Hammer explicitly works with pine, crystal, pellet and clumping, and lighter pine and pellet litters leave the box in a lighter scatter than dense clay regardless of the box.
How to Transition Your Cat to a Top Entry Box in 5 Steps
The jump is the only real obstacle, and it is almost always habit rather than ability. The most reliable approach owners report runs over one to two weeks and never involves forcing the issue.
Step one, place the new box beside the old one. Not on top of it and not in a different room. Put the two next to each other with the same litter and let the cat use whichever it prefers. Owners report this as the single most successful tactic, and a cat that keeps choosing the old pan is telling you the jump is not the problem.
Step two, move used litter into the new box. Familiar scent matters more than familiar geometry. Transfer a few handfuls of soiled litter from the old box so the new one does not smell like a stranger, and repeat this every day or two during the transition.
Step three, leave the lid off at first. A top entry box with the lid removed behaves like a front entry box. Several days of unrestricted access removes the barrier and lets the cat settle on the litter and the location rather than the design. This is the most useful fallback if a cat sniffs the top entry and walks away.
Step four, replace the lid and open the alternatives. Once the cat is using the box without the lid, put the lid back on. If it hesitates, use a convertible box in front entry mode, such as the Marchul, so the cat has an easy route while it builds the new habit.
Step five, remove the old box only after consistent use. Wait until your cat has used the new box reliably for a week or more, then take the old one away. In a two-cat home, keep the second box as a second exit route rather than removing it entirely, because a single-exit top entry box is a real risk if one cat is dominant.
One safety note. If your cat is a kitten under four months, a senior with joint pain, or a long-bodied breed that cannot manage the opening, skip top entry entirely for now and use a front entry box instead. The transition will not fix a mobility limit.
Troubleshooting: When a Cat Avoids a Top Entry Box
Most refusals have a specific cause, and the cause determines the fix. These are the four failure modes we see most often, with what actually works.
If your cat pees or poops on top of the lid, the cat has accepted the box but not the entry. Either the opening is too small for its body, or the jump is too high, or the surface is slippery. Widen the entry with a lower-profile box, put the box somewhere the cat can land comfortably rather than at the edge of a counter, and clean the lid thoroughly so no scent remains. If the cat stands to pee, the wall height is usually the problem, and you need a box with taller sides.
If your cat jumps straight over the box, no design will help until the box itself is the obstacle. Put it in a corner or between two pieces of furniture so the escape route is blocked, or place the box on a low surface where landing elsewhere is not an option. A convertible box set to semi-enclosed or open also removes the temptation to leap.
If urine pools under the entry hole or in the lid seam, the geometry is working against you. Wipe the seam after every use, dry it, and consider a design with an overlapping panel seal and a leak-proof base panel such as the FZGhome, or a full-height seamless base such as the Modkat. A mat under the box protects the floor until you change the box.
If your cat chews the scoop hook or claws the lid hinge, the hook is a dangling toy and the hinge is a noise source. Snap the scoop clip off or store the scoop away from the box, and check the hinge latch periodically because a cracked hinge on the Arm and Hammer model is a common and predictable failure.
Two more fixes worth knowing. If litter still reaches the floor after a fortnight, add a mat outside the box rather than replacing the box, because the leak path is usually paw dust at the final step. And if odor is the complaint, switch to a stainless pan, or add a carbon-filtered hood, since walls alone will not hold odor inside an enclosed shell.
Who Should Not Buy a Top Entry Litter Box
This format is not right for every cat, and buying one for the wrong cat is the most common reason they end up unused.
Senior and arthritic cats. The jump in and out is real exertion, and a cat with joint pain will decline rather than complain. The Marchul and the TENTIZON both open a front door for exactly this reason, but a genuinely arthritic cat belongs in a low-sided open or semi-enclosed pan.
Kittens under about four months. Their coordination is not there yet, and the risk of an injury on the way out is not worth the tracking benefit. Use a shallow open box with low sides until they are steady, then transition up.
Blind cats and cats with low vision. A top entry box requires a cat to judge a hole in a lid from above, which relies on depth perception. A blind cat will usually manage an open or front entry box far better. Our test setup included no blind cats, so treat this as reasoning from the mechanics rather than from observation.
Very long-bodied breeds that cannot turn. A Norwegian Forest Cat, a Maine Coon or any cat over about 15 lb needs a long interior, and the Modkat at under 16 inches square is the wrong shape for them. Check the internal length against body length before buying any enclosed box.
Multi-cat homes with one dominant cat. A single exit point is a genuine risk if a smaller cat gets blocked. Use a convertible front and top entry box, or run two boxes in separate locations, so every cat has a way in and a way out.
Frequently Asked Questions
What is a good litter box with a top entry lid?
A good top entry litter box has a perforated, grated or grooved lid that returns paw litter to the pan, walls at least 13 inches tall, and an entry opening wide enough for your cat to pass through without turning sideways. In this roundup the IRIS USA Large Top Entry Cat Litter Box is the strongest all-round pick, with a 9 inch wide entry and a 4.6 rating from more than 34,000 reviews.
Do top entry litter boxes stop litter tracking?
They reduce it substantially rather than eliminating it. The high walls stop litter being kicked sideways while digging, and the lid strips litter off the cat’s paws on the way out, so far less reaches the floor than with an open pan. A cat that jumps straight over the lid bypasses the mechanism entirely, so an outside mat is still worth keeping in a heavy-tracking home.
How do I get my cat to use a top entry litter box?
Put the new box beside the old one with the same litter and let the cat choose. Move a few handfuls of soiled litter into the new box, and leave the lid off for several days so the box behaves like a front entry box. Once the cat is using it reliably, put the lid back on and remove the old box after a week of consistent use.
Can kittens use top entry litter boxes?
Not young ones. Kittens under about four months lack the coordination for the jump in and out, and the risk of a fall makes a shallow open box with low sides the safer choice. Once a kitten is four months and steady on its feet, a top entry box works, and the So Phresh is listed as suitable from one month up for supervised use.
Are top entry litter boxes okay for senior cats?
They suit healthy senior cats, and many adapt to the jump within days. A cat with joint pain or arthritis is the exception, and a convertible box with a front door such as the Marchul, or the TENTIZON with its 6 inch swinging front door, avoids the jump entirely. A blind cat is also better served by a front entry box, because judging a hole from above relies on depth perception.
Which litter works best with a top entry litter box?
Any clumping litter works in a box with a smooth or stainless pan, and the Arm and Hammer model is rated for pine, crystal, pellet and clumping litter. Lighter pine and pellet litters track less than dense clay because they fall off the paws in a lighter scatter, so switching litter can reduce tracking before you change boxes.
What is the best top entry litter box for large cats?
The FZGhome Stainless Steel XL Litter Box is the largest in this roundup at 23.65 inches long, and the TENTIZON publishes a cat weight range of 3 to 18 lb. The IRIS USA Large Top Entry box is the pick with the widest entry opening at 9 inches, which is what matters most for a senior or heavy cat that struggles to pass through a narrower hole.
What is the best open top litter box?
If you want a top entry design without a lid, a semi-enclosed mode box is the compromise. The FZGhome, the KISENG and the Marchul all convert from fully enclosed to semi-enclosed or open, so you can remove the entry jump without buying a separate open pan. A true open top pan is better for kittens, seniors and very long-bodied cats than any enclosed box.
Final Verdict: The Best Top Entry Litter Box for Litter Tracking in 2026
The IRIS USA Large Top Entry Cat Litter Box takes the top spot. Its 9 inch wide entry, grooved litter trap, seamless base and a review base of more than 34,000 ratings at 4.6 stars make it the pick we would put in almost any home, and it is the one our tracker used without supervision.
Buy the Arm and Hammer Premium box for the best grated litter catch and Microban odor control, the Modkat if you want the most refined design and dislike disposable liners, and the TENTIZON or FZGhome if odor or a very large cat is your priority. Add a mat outside whichever you choose, and give your cat two weeks before you judge the format.
