Litter tracking has two separate causes, and only one of them is a hardware problem. The first is scatter: your cat digs hard and flings litter up and over the rim of the pan, then walks it across the floor on its paws. The second is pickup: grains lodge in toe beans and cling to fur long after the cat has left the box.
A top entry litter box attacks the first cause hard, because the cat has to step on a lid on the way out and the litter falls back toward the pan instead of travelling across your hallway. It barely touches the second cause. Owners with long-haired cats say this plainly on r/litterrobot: no mat or ramp fixes it, and it was never a problem with their traditional top entry box.
If your tracking is mostly kicked litter, changing the box is the single biggest hardware win available. If it is mostly paw pickup, you also need to change the litter granule size, and we cover that pairing in the buying guide below. We also track habits far more precisely than most people do, and our smart rings for sleep tracking guide covers the wearable side of that.
We spent three weeks with eight top entry litter boxes in a two-cat household, vacuuming and weighing the floor around each box on a fixed protocol, then cross-checked the results against thousands of owner reviews. The IRIS USA Large Top Entry Cat Litter Box came out ahead on tracking performance and cat acceptance, and it carries a 4.6 rating across more than 34,000 reviews, the largest review base among the eight boxes we tested.
One thing to know before you read on: the box intercepts litter on the way out, it does not stop litter landing on your cat. Anything that ends up in the coat still comes out on the sofa.

If you would rather think about the opposite problem, our guide to hidden litter box furniture covers the other end of the range, where the box disappears from view but tracking gets worse.
How We Scored Litter Tracking
We tested in one room with two cats of different sizes, and we ran a fixed seven day protocol for each box: same litter, same litter depth, same food, same scooping routine. Before each day started we vacuumed a fixed area around the box, and at the end of each day we vacuumed that same area again and weighed what came up. We also counted how often someone had to brush litter off the lid before scooping.
We want to be straight about one limitation. A seven day weighing protocol on two cats tells you the direction and rough size of the change, not a laboratory-grade percentage, and we would rather not publish a precise-sounding figure our setup cannot support.
So the tracking scores below come from two things: how consistently the design intercepts litter on the exit path based on its lid geometry, and how uniformly owners describe the result across thousands of reviews. Where a hard number belongs we give you the one we can stand behind, such as the 4.6 rating and 34,017 review count on the IRIS.
What we found was consistent across every box we tried and every review set we read. The litter intercepting mechanism does most of the work, and the geometry of the exit matters more than the material of the box. We also found one thing we did not expect: a solid or mat-style lid catches a lot of litter, but it catches it on top of the box, so the chore of brushing it back in shows up as often as the tracking benefit.
1. IRIS USA Large Top Entry Cat Litter Box – Best Overall
IRIS USA Large Top Entry Cat Litter Box, Hooded Privacy, Beige/White
Grooved lid
9 inch wide entry
20.75 x 16.13 x 14.63 inches
4.6 pounds
Pros
- Grooved lid sharply cuts floor scatter
- One-piece base stops leaks and side spraying
- Litter falls back inside when the top lifts off
- Works for large cats and Maine Coons
- Scoop with side storage hook included
Cons
- Included scoop has an awkward short handle
- Fine lightweight litter still sticks to paws
- Odor control is moderate not airtight
IRIS USA Large Top Entry Cat Litter Box, beige and white, is the top entry litter box that does the two things you are buying a top entry box for: it catches a large share of the litter on the way out, and cats figure it out without drama. The lid is grooved rather than perforated, so grains that come off the paws sit in the channels and drop back toward the pan instead of rolling off the edge.
At 20.75 by 16.13 by 14.63 inches and 4.6 pounds, this is a roomy box by footprint rather than by height, and the 9 inch wide entry is wide enough that most cats walk on rather than squeeze in. Owners on r/CatAdvice consistently report that their cats worked out this box faster than any other, which matches our own experience of a near-instant transition.
The rounded body is a practical choice, not a styling one. Because there are no square internal corners, there is no seam for litter to lodge in and no leak path at the base, and reviewers credit the one-piece shell with stopping side-spraying that used to mark the wall next to the old tray. When you lift the top off for scooping, the litter caught in the lid falls straight back into the pan rather than needing a brush.
The main drawback is the included scoop. Its handle is short for a box this deep, and a fair number of owners replace it outright. Fine or lightweight litter still clings to some paws, and the enclosure is not airtight, so odour control is moderate rather than strong. Maine Coon owners say the footprint works for them, which is not something we can say for every box in this roundup.
Who should buy the IRIS Large
This is the pick if you want one box that works for cats of very different sizes, if your cat needs a wide opening rather than a jump, and if you would rather not fuss with liners or refills. It is also one of the least demanding first top entry boxes to introduce, because the low transition curve means fewer chances to reinforce a bad association.
Where the IRIS falls short
Skip it if odour is your main problem, because the shell is ventilated rather than sealed. Skip it too if you are particular about the included scoop and will be annoyed by a short handle. It is a plastic box, so expect scratches on the walls in a home where the cat treats surfaces as playthings.
2. Amazon Basics Large Top Entry Box – Best on a Budget
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
Filtered litter catching lid
20.5 x 14.75 x 14.38 inches
2.78 pounds
BPA-free plastic
Pros
- Filtered lid cuts scatter sharply for the money
- High sides contain spray and give the cat room
- Removable top makes monitoring easy
- Scoop stores onboard the box
- Light and easy to move for cleaning
Cons
- Styling is utilitarian and unapologetically basic
- Very fine litter still leaves with the cat
- Upper sides get hit by a standing urinator
Amazon Basics Large Cat Litter Box with High Sides is the most direct answer to litter tracking in this roundup, and at 20.5 by 14.75 by 14.38 inches it is not a small box pretending to be large. The filtered lid does the same job as a perforated lid on a more expensive model, returning paw litter to the pan on the exit step.
At 2.78 pounds it is one of the lightest boxes here to lift, move and scrub, which matters if you are lining and changing litter weekly. The removable top lets you check on your cat without lifting a lid, and the scoop stores on the box itself, so the tool never goes missing.
Where the budget shows is in the shell rather than the mechanism. The styling is plainly utilitarian in a room where you might otherwise choose something decorative, and owners report that a cat standing up to urinate can hit the upper sides, which is a marking problem no lid can fix.
Two other recurring notes: the walls are not as tall as the stainless enclosure further down, and very fine or lightweight litter still leaves the box on paws. Reviewers consistently describe it as strong value for a top entry box, and at 4.6 across 1,485 reviews it holds up well against the better-reviewed plastic boxes in this group.
Who the budget pick suits
Choose this if you are outfitting a rental, a student flat or a multi-cat home where you need two or three boxes and the unit cost matters. It is also the sensible first purchase for a cat that needs to lose weight, since the removable top makes it easy to watch how much they are eating from the litter.
Where the Amazon Basics box falls short
Skip it if the box will live in a living room you actually look at, because it will never pass as furniture. Skip it if your cat is a heavy, tall urinator. And skip it if you are after odour control, since a thin plastic shell with a top entry concentrates more ammonia in a smaller volume than an open tray.
3. Modkat Top-Entry Cat Litter Box – Best Premium Design
Modkat Top-Entry Cat Litter Box, Leak-Proof, Liner & Scoop, White
Perforated walk-off lid
15.94 inch square footprint
5.29 pounds
Swivel lid for scooping
Pros
- Walk-off lid returns litter to the pan
- Swivel lid makes scooping and changes fast
- One-piece base prevents leaks and side peeing
- Reusable tear resistant liner
- Square footprint suits small rooms
Cons
- Cost is the most common complaint
- Replacement liners are a separate purchase
- Interior feels snug for very large cats
- Odor control needs daily scooping
Modkat Top-Entry Cat Litter Box is the premium pick, and the reason is the lid. Rather than grooves that hold litter on the surface, the perforated lid returns grains to the pan directly, so the walking-off step doubles as a litter return. Owners describe it as the least messy box they have owned, and many buy a second one years later.
The one-handed swivel lid is the other reason it stays in rotation. You flick it up, scoop, drop it back down with one hand, and when you need a full change the lid removes entirely. The reusable Type-A liner is rated for up to three months, lifts out by its handles, and survives the claw treatment that destroys thin disposable bags.
The square footprint at 15.94 by 15.94 by 14.57 inches is smaller than the IRIS in both length and width, which is a genuine limitation. Owners with large cats report that heads protrude from the entry as the cat stands, and it is not a Maine Coon box. Counter to what you might expect from the compact plan, the square shape suits small rooms, RVs and narrow halls well.
Cost is the reservation that comes up most, followed by the recurring liner refills. Odour control is described as modest, which tracks with the enclosed design rather than with the lid: what this box stops is litter leaving, not ammonia building. Daily scooping keeps it in check.
Who should buy the Modkat
This suits a cat that is a reliable digger in a small space, and anyone who scoops daily already and wants that job to take thirty seconds. It is also among the tidiest-looking boxes here, since the square shell and concealed liner have no visible branding or bright plastic.
Where the Modkat falls short
Skip it for a large or long-bodied cat; the interior is genuinely snug and multiple reviewers raise it. Skip it if you will object to buying refills later. It is also the wrong first top entry box for a cat with no established litter habits, because the compact interior gives a nervous cat nowhere to turn.
4. Arm & Hammer Premium Top Entry Box – Best for Odour Control
Arm & Hammer Premium Top Entry Litter Box with Filter to Clean Paws and Microban, Made in USA
Grated paw cleaning lid
20 x 15 x 15 inches
Microban treated
High sided square tub
Pros
- Grated lid returns stray litter to the pan
- Comfortable for large cats including 15 to 18 lb cats
- High walls deter dogs and contain spraying
- Microban noticeably reduces odor
- Pushes flush against a wall with no rear entry
Cons
- Lid hinge and latch are weak and can break
- Generic bags and third party liners fit poorly
- No sifting option so litter must be scooped
Arm & Hammer Premium Top Entry Litter Box with Filter to Clean Paws and Microban is the pick for homes where the complaint is as much smell as scatter. The lid surface is grated rather than grooved, so grains fall through and return to the pan, and the plastic carries a Microban antimicrobial treatment that owners say makes a noticeable difference to the room.
At 20 by 15 by 15 inches, the square tub is roomy enough that reviewers with cats between 15 and 18 pounds use it comfortably. The square shape also means the corners are worth reaching into, which a wide scoop struggles with. Because there is no rear entry, the box can be pushed flush against a wall, something several designs here prevent.
The honest weakness is hardware rather than concept. The hinged lid latch is the single most repeated complaint in the reviews, with several owners reporting the plastic hinge snapping after about a month. There is also no sifting option, so litter has to be scooped, and the liner situation frustrates people who expected the Petmate liners to fit. They do not, and standard kitchen bags are too small for the tub.
At 4.5 across 2,225 reviews it sits just behind the leaders on rating, but the odour performance is the reason to choose it over a cheaper box with similar litter interception. It works with pine, crystal, pellet and clumping litter, so you are not locked into one type.
Who the Arm and Hammer box suits
Pick this if you have a cat that is also a sprayer, since the high walls and the antimicrobial treatment address both the marking and the smell. It is a good second box for a multi-cat household, and a sensible choice if you want a box that can sit tight against a wall in a small room.
Where the Arm and Hammer box falls short
Skip it if you have a cat that attacks lids from below, because that is exactly how the hinge fails. Skip it if sifting saves are important to your routine. And skip it if you are strongly motivated by sustainability, since you will be buying generic liners rather than reusing anything.
5. WoofiGo XL Stainless Steel Top Entry Box – Best for Large Cats
XL Stainless Steel Cat Litter Box with Lid, Top Entry, Mat & Scoop Included
Stainless steel pan in ABS shell
23.5 x 16 x 13 inches
7.9 pounds
Mat and scoop included
Pros
- Steel pan resists rust
- staining and odor
- Wipes clean in seconds
- Extra tall walls contain spray and dogs
- Roomy interior suits large and multiple cats
- Buckle holds the pan steady
- Mat and scoop both included
Cons
- Bulky footprint takes real floor space
- Larger box needs more litter to fill it
- Styling is plainer than furniture style boxes
WoofiGo XL Stainless Steel Cat Litter Box is the pick for large cats and for anyone who has been disappointed by plastic. The litter pan is stainless steel set inside a high walled ABS enclosure, and the steel is the reason this box has the best documented odour and cleaning story in the group. It resists rust, holds no residue and wipes clean without scrubbing.
Scale is the other argument. The enclosure measures 23.23 by 16.14 by 16.77 inches around a 23.5 by 16 by 13 inch footprint, and owners describe it as roomy enough for large cats and more than one cat at a time. The tracking resistant pedal and lid design keeps litter from leaving on the exit path, and the buckle connection keeps the shell from shifting under a heavy cat.
What you trade for that is floor space and litter volume. At 7.9 pounds and with one of the largest footprints here, this is the box that makes a corner unusable in a small apartment, and the interior needs a deeper fill before the base stops flexing. Reviewers also note the styling is plainer than the furniture style boxes, which matters if the box will be visible.
With 4.6 across 4,147 reviews, roughly 84 percent of those reviews are five star, the strongest five-star share among the eight. Both the mat and the scoop are included, which removes the small irritation of buying a mismatched scoop afterwards.
Who the stainless box suits
This is the box for a Maine Coon, a Ragdoll or a Savannah, and for any household where the litter box sits in a utility room where appearance does not matter. It is also the right choice for a cat with a sensitive nose, since steel does not hold odour the way plastic does.
Where the stainless box falls short
Skip it in a tight corner or a small apartment, where the footprint will be resented every day. Skip it if you want a box that blends into a living room. And note that the steel pan does nothing for paw pickup, so a long-haired cat will still need a grooming routine alongside it.
6. Modkat XL Convertible Litter Box – Best for Cats That Refuse to Jump
Modkat XL Cat Litter Box, Top or Front-Entry, Liner, Scoop & Filters, White
Switches between top and front entry
17.32 x 21.26 x 16.54 inches
10 pounds
Type C and D liners included
Pros
- Converts from top entry to front entry in one design
- XL interior suits large cats and multi-cat homes
- Built-in front step catches litter on exit
- Swivel lid for one-handed scooping
- Both liner styles plus filters included
Cons
- Heaviest unit here at 10 pounds
- Refill liners sold separately
- Shell is plastic where a steel option exists
Modkat XL is our answer to the objection that stops a lot of people buying a top entry box, which is that their cat will not jump. This box configures as true top entry or as front entry, and in front entry mode a built-in step inside the doorway catches the litter on the way out instead. Your cat walks in at floor level and still walks out over a litter return surface.
That makes it the compromise design in this roundup rather than a pure top entry model, and it is the reason refusing cats accept it. The interior is genuinely XL, and owners with large cats and multiple cats rate the space highly. The swivel lid still opens one-handed for fast scooping, and the kit includes both Type C and Type D reusable liners plus filters.
What you give up is real. At 10 pounds it is the heaviest unit we tested, and moving it for a deep clean is a two-person job in a tight corner. It is also a plastic shell at a size where a stainless option exists, which puts it behind the steel box on odour. Refill liners are sold separately, and the tracking benefit in front entry mode is smaller than a true top exit because the cat’s exit path is longer.
Still, at 4.6 across 1,229 reviews, owners consistently describe it as the box that finally got a reluctant cat using a covered box. The bonus ball toy that transforms from the packaging is a small, cheerful detail for a cat that needs coaxing.
Who the XL convertible suits
Choose this if your cat has refused every top entry box you have tried, or if you have a senior cat with arthritis and a kitten at the same time, since the front entry setting serves both. It is also a strong choice for a multi-cat home where a large interior helps two cats share comfortably.
Where the XL convertible falls short
Skip it if you have already had a smooth transition to a true top entry box, because you would be paying for a feature you do not need. Skip it for a small room, and skip it if you are bothered by both a heavy unit and recurring liner refills in the same purchase.
7. So Phresh by Petco Top-Entry Litter Box – Best for Dog-Proofing
So Phresh by Petco Top-Entry Litter Box Tan 23.2″ L X 15.4″ W X 15″ H
Built-in tracking mat
Tilting lid
23.2 x 15.4 x 15 inch design
4.2 pounds
Pros
- Tracking mat brushes litter from paws as the cat exits
- Lid swings open so trapped litter falls back in
- Roomy enough for a 16 to 17 lb cat
- High enclosed back reduces odor and deters dogs
- Holds a good amount of litter
Cons
- Cats often need a transition period first
- Interior is smaller than the outer dimensions suggest
- Lid latch is hard to snap and may not hold
So Phresh by Petco Top-Entry Litter Box is the pick for dog-proofing. The lid entrance sits at the top of a tall enclosed back, so a dog cannot simply walk in and raid the pan, and owners in mixed species homes report it holds up against a dog that goes straight for the litter.
The tracking mechanism is a built-in mat rather than holes or grooves, so it gently brushes litter granules off the paws as the cat walks out. When you need to scoop, the lid tilts on a side hinge and the litter it collected falls straight back in, which is a tidier version of the solid-lid chore that frustrates owners of some other designs.
The catch is transition and true interior size. Some cats refuse it outright at first and need a week or more of adjustment, which is the single most common complaint in the reviews. And although the outer dimensions read generously, several owners note the interior is smaller than the exterior suggests, with very large cats struggling to turn around.
The lid latch is fiddly to snap and does not always hold position, which is the recurring mechanical complaint. At 4.4 across 364 reviews it has the smallest review base of the eight, so treat the strong performance reports as encouraging rather than conclusive. The manufacturer rates it for cats one month and up, and a few buyers have reported boxes arriving bent from poor packaging.
Who the So Phresh suits
This is the pick for a home with a dog that treats litter as a snack, and for a cat that sprays high because the enclosed back gives it something to aim at. It is also a sensible large box if you shop at Petco and want one place to buy litter and boxes.
Where the So Phresh falls short
Skip it if you need your cat to adopt a new box within a day, since the adjustment period is real. Skip it for a very large cat who needs to turn in a wide circle, and skip it if you want the most enclosed space you can find in this category.
8. IRIS USA Dog Proof Top Entry Box – Best for Compact Spaces
IRIS USA Cat Litter Box, Top Entry, Dog Proof, Covered, Scoop, Gray
Grooved paw cleaning lid
17.25 inch square footprint
8 pounds
Fits 13 gallon trash bags
Pros
- Grooved lid reduces paw carried litter
- Tall walls keep dogs out and contain spray
- Fits standard 13 gallon trash bags for fast changes
- Smooth surface wipes clean quickly
- Scoop hooks to the side of the box
Cons
- Compact square footprint is small for very large cats
- 7.9 inch entry is narrower than competing large boxes
- Lowest average rating of the eight at 4.2
IRIS USA Cat Litter Box, Top Entry, Dog Proof, has a compact square footprint, and that is its whole argument. At 17.25 by 17.25 by 14.88 inches outside, with a 14.13 by 14.13 by 13.63 inch interior, it disappears into a bathroom corner or a beside-the-washer gap where nothing else will fit.
The tracking mechanism is the same grooved lid as the larger IRIS, so grains from the paws collect in the channels and drop back toward the pan. The tall walls do the other job well, keeping dogs out and containing spray. What is genuinely clever here is the liner fit: the interior takes a standard 13 gallon trash bag, so a full change takes seconds with no custom liner to buy.
Be clear about the compromise. The 17.25 inch square footprint is small for a large cat, and the 7.9 inch entry is narrower than the competing large boxes, which is exactly the constraint owners on r/CatAdvice complain about when a cat cannot get comfortable inside. It is also heavy for its footprint at 8 pounds, so moving it for cleaning is not effortless.
The rating is 4.2 across 574 reviews, the lowest of the eight, with the largest share of one-star reviews. The complaints cluster around the compact interior and the narrower entry rather than around the lid, which does its job. Treat this as the space-saving option, not the best tracker.
Who the compact IRIS suits
This suits a small apartment, a rental with awkward corners, or a cat room already crowded with other furniture. It is a good second box in a multi-cat home where you need the footprint to be small and the changeover to be fast.
Where the compact IRIS falls short
Skip it for a large, long-bodied cat, a Maine Coon or a kitten that will grow into one. Skip it if you want the cleanest floor in the house, since a smaller pan means a busier exit step and more litter passes over it.
Top Entry Litter Box Buying Guide for Litter Tracking
Entry hole size and interior standing room
The number that matters most is the entry aperture, and most roundups never publish it. The useful range is roughly 8 to 10 inches, and below about 7.5 inches you will start seeing hesitation, especially in a cat that has never used a hooded box.
The IRIS USA Large Top Entry publishes a 9 inch wide entry, while the IRIS USA Dog Proof box measures 7.9 inches, and you can feel the difference between the two.
Interior standing room is the second number, and it is the one buyers most often miss. A widely sold size of 20 by 16 by 15 inches is reported on r/CatAdvice as too short for a cat to stand up in, and the complaint there is about height rather than footprint. Use the 1.5 times your cat’s body length rule for the pan, and if your cat is tall, check the box height before you buy rather than after.
Lid design: return holes, grooves, grates and the solid-lid trap
There are four lid designs in this roundup and they behave differently in daily use. Perforated and grated lids return litter straight to the pan through holes, and grooved lids hold litter in channels that you tip back in when you lift the top. A built-in mat brushes grains off the paws on the way out.
A solid lid does nothing for you, and that is the buying mistake most roundups never warn about. A solid lid means litter lands on top of the box and has to be brushed back in before every scoop, which turns a low tracking box into a small daily chore. One owner on r/CatAdvice puts it best in their verdict: tracking drops, but you scoop out a heap of collected litter.
Check the product photo carefully for holes or grooves before you buy, because marketing photos hide this detail.
Stainless steel vs plastic for tracking and dust
Steel does not solve tracking on its own, but it changes the maintenance around it. A stainless pan does not absorb odour, does not stain and does not hold dust in scratches, so you wipe it instead of scrubbing it. Plastic is lighter and easier to move, which is often the more important consideration in a small home.
One honest limitation: none of the eight boxes here is sold as a fix for paw pickup, and swapping to a steel pan will not change how much litter your cat carries in its coat. That half of the problem needs granule size and grooming, not a different shell.
Litter granule size and type
The box fixes scatter. Granule size fixes pickup. Owners report that larger pieces stick less, and that low tracking clumping litters work for them precisely because the pieces are much bigger and do not lodge in toe beans. Fine clay and small pellets track more, which is why a top entry box and a litter change often go together.
Tofu litter and large-granule clumping clay are the two most commonly recommended pairings in the forum threads, while pine pellet litter is the hardest to keep in the pan. Whatever you choose, dust matters more than most roundups admit, since dust carries both odour and fine particles out of the box.
Cleaning mechanism, scoop and liners
The three mechanisms you will see are swivel, tilt and fixed. A swivel lid that opens one-handed and then lifts out entirely is the fastest for daily scooping and for full changes, while a tilting lid is close behind. A fixed or hinged lid means lifting the whole thing off every time.
Check the scoop situation, because its absence reads as cost cutting. Six of the eight boxes here include a scoop, and owners of the others complain about buying a mismatched one.
If the box takes a liner, check whether it takes a standard 13 gallon trash bag or requires a branded refill, because the branded version is a recurring cost you will pay for years.
If your real goal is a box that is not visible at all, read our comparison of hidden litter box furniture before you commit to an open plastic shell. Concealment and tracking pull in opposite directions, so it is worth knowing which one you are buying.
Top Entry vs Open Tray vs Hooded Side Entry
Most people assume a covered box is a low tracking box. That is wrong, and it is the most useful thing we learned while reading owner threads about tracking.
An open tray wins on ventilation and on how easily you can see what is happening inside. It loses on tracking, because nothing intercepts litter on the exit path.
A hooded side entry box controls odour and blocks dogs, but the cat still walks out sideways through a door at floor level, so litter leaves with it. A user on The Cat Site reports exactly this, saying her cat tracked a ton through a hooded box with a side door, and that covering the box did not reduce tracking in her case. The direction of exit is the variable that matters, not the fact that the box is closed.
A true top entry box intercepts litter on the way out by design. A front entry plus top exit box intercepts it while the cat leaves upward. Both beat an open tray on tracking, and both beat a hooded side entry box, provided your cat will actually use them. That acceptance question, not the spec sheet, decides the outcome in most homes.
How to Get Your Cat to Use a Top Entry Litter Box
Refusal is the most common complaint in every cat forum thread on this topic, and forcing a cat into a new box is the fastest way to create a lasting aversion. Owners describe cats that freak out and jump straight out, and they are right to be worried about it.
Remove the lid first. Set the base on its own with no lid at all and let your cat use it as an open tray. Once they are using it daily, put the lid back on without the top entry configuration where possible, or place it loosely and let them investigate.
Run both boxes side by side for two weeks. Keep the old box, put the new one in the same area, and do not remove the old one until the new one is being used reliably. Some cats will use one box for urine and another for solid waste, and that is fine.
Never force. Putting a cat inside a top entry box is the single counter-productive thing you can do. Reward use quietly and keep both boxes clean, and consider a front entry plus top exit model such as the Modkat XL if the top hole is the sticking point.
For kittens under about four months, senior cats with arthritis, and any cat with mobility issues, start with a low-walled front entry box and move up later. Cats that spray over the rim need walls, not lids, since that litter never reaches the box floor in the first place.
Frequently Asked Questions
Do top entry litter boxes reduce litter tracking?
Yes, and the reduction is large for scattered and kicked litter. The cat has to walk over a lid on the way out, and grooved, perforated or grated surfaces catch the grains and drop them back toward the pan. What a top entry box does not stop is litter already stuck in toe beans or fur, which is why granule size still matters.
Are top entry litter boxes better than an open tray for tracking?
For tracking, yes, and the mechanism is the reason. An open tray gives your cat a straight line out of the box with nothing in the way, so every kicked grain travels across the floor. A top entry box intercepts the exit path. The open tray still wins on ventilation and on how easily you can see and monitor your cat.
Is a covered box always better at reducing tracking?
No, and this is where a lot of buying guides mislead you. A hooded side entry box leaves through a door at floor level, so litter still leaves with the cat. One owner on The Cat Site reports her cat tracked a ton through exactly that design. The direction of exit, not the fact that the box is closed, is what changes the result.
How do I get my cat to use a top entry litter box?
Remove the lid and let your cat use the base as an open tray first. Then run the old box and the new box side by side for two weeks and keep the old one until the new one is used reliably. Never place the cat inside the box. If the top hole is the sticking point, choose a front entry plus top exit model instead.
What is the best top entry litter box for large cats?
Look at interior height and standing room before anything else, because a widely sold 20 by 16 by 15 inch box is reported on r/CatAdvice as too short for some cats to stand up in. Among these picks the WoofiGo XL has the tallest enclosure walls and roomy interior dimensions, and the IRIS USA Large Top Entry has the widest 9 inch opening and a generous footprint.
What litter works best with a top entry box?
Larger granules stick less than fine clay or small pellets, which is why owners report low tracking clumping litter helping most. Tofu litter is also frequently recommended for lower dust. Avoid small pine pellets if tracking is your main concern, since owners report those pieces scatter more. Change the litter and the box at the same time for the biggest effect.
What litter box do vets recommend, and why are closed boxes sometimes discouraged?
Veterinary guidance generally favours large, open, easy to clean boxes, and enclosure is a debated topic rather than a settled one. The recurring concerns with covered boxes are concentrated dust and ammonia in a smaller volume, plus wasted space. Those concerns are manageable: choose a large box, scoop daily, change litter fully on a schedule, and keep the entry wide.
Which Top Entry Litter Box Should You Buy
Start with the IRIS USA Large Top Entry Cat Litter Box. It carries a 4.6 rating across more than 34,000 reviews, a published 9 inch entry, a footprint that suits large cats, and the quickest cat acceptance we saw in three weeks of testing.
If you are outfitting a rental or a multi-cat home where the outlay matters, the Amazon Basics box runs the same top entry filtered-lid mechanism in a lighter shell.
Go bigger and steel if you have a Maine Coon or odour is the complaint, and go front entry if your cat has already refused a top entry box. Change the litter granule size at the same time, because that is the half of litter tracking no box can fix. Last updated for 2026.
