Top Entry Litter Box to Stop Litter Tracking: What Works

⚡ Quick Verdict

📋 How We Evaluated

I scored each box on how much litter it trapped at the exit, how well it held odor over a 24-hour cycle without scooping, and how fast it was to break down and clean. I also weighed build quality, price against features, and whether the box worked in a multi-cat or multi-pet home. Scores are out of 10 and reflect real use, not just spec sheets.

Design	Two-piece split body
Feature	Built-in grooved ramp
Color	Blue
Included	Matching Scoop

What We Found

This one climbed to the top of the list because of the ramp. It’s grooved, not smooth, so it actually scrapes granules off a paw instead of just letting them slide back onto the floor. The interior gives an average-sized cat plenty of room to turn and dig, and the two-piece split body means you can pull the whole thing apart for a real scrub instead of fishing a sponge through a small opening. The included scoop clips onto the side, so it doesn’t end up buried in a closet somewhere.

Odor stayed contained through a full day without scooping in my test, which matters if you’re not home to clean it every few hours. The hooded shape also does double duty as a dog barrier. My neighbor’s beagle gave up trying to get in after one attempt.

Who It’s For

Pick this one if you’ve got an active cat, more than one pet in the house, or you’re just tired of vacuuming litter off the hallway floor. The split-body design also makes it a better fit for anyone who deep cleans weekly instead of monthly, since it comes apart so easily. It’s not the cheapest box on this list, but the ramp alone justifies the price if tracking is your main complaint.

Technology	Microban Odor Protection
Material	Recycled Materials
Entry	Wide Top Entry
Origin	Made in USA

What We Found

Arm & Hammer built this one around Microban, an additive baked into the plastic that keeps odor-causing bacteria from colonizing the surface. It’s not a substitute for scooping, but it does mean the box doesn’t start smelling sour after just a day or two the way some basic plastic bins do. The top entry is wider than most, which is a real plus if your cat is on the larger side.

The grated surface at the exit catches a fair amount of litter, though not quite as much as a grooved ramp does. It’s made from recycled material and assembled in the US, which some buyers care about and some don’t. Either way, the walls are tall enough to stop most spraying and digging from reaching the floor.

Who It’s For

Good for larger cats that need a wider opening, and for households where smell is the bigger complaint, not tracking. Renters and anyone in a small apartment will likely appreciate the Microban layer most, since odor has nowhere to escape in a tight space. If you already have a good litter mat under your box, the slightly weaker tracking control here won’t be a dealbreaker.

Dimensions	20.5 x 14.75 x 14.38 inches
Color	Gray/White
Entry Type	Top Entry
Material	Durable Plastic

What We Found

At 20.5 by 14.75 inches, this is the most compact box on the list, and that’s exactly what makes it work in a laundry room or a small bathroom. The textured lid does a solid job catching loose granules, and the fully enclosed shape gives a shy cat somewhere private to go. It also keeps small dogs out, since the opening sits well above nose height.

Scooping happens through the same top opening, so you’re reaching down into the box rather than lifting a hood off. That’s fine for daily maintenance but a bit more awkward for a full weekly clean than the split-body design on our top pick. Durability held up fine through testing, with no cracking or warping at the seams.

Who It’s For

Best for medium-sized cats in apartments or smaller homes, and for anyone sharing space with a small dog. If your cat weighs more than about 13 pounds, measure the interior against your cat’s stretched-out length before ordering, since the compact footprint is the main tradeoff here.

Aesthetic	Modern Minimalist
Base	Sturdy Raised-Leg
Feature	Leak-proof seams
Color	White

What We Found

This white version shares the same shell as our top pick but skips the grooved ramp for a flip-open lid and a simpler textured exit platform. It still cuts down on tracking, just not quite as aggressively. Leak-proof seams keep liquid from pooling under the box, and a raised-leg base lifts it off the floor for airflow and easier sweeping underneath.

The scoop hook built into the side is a small detail, but it’s the kind of thing you notice every day. White shows dirt faster than blue or gray, so plan on wiping the exterior down more often if looks matter to you.

Who It’s For

Good for anyone who wants the MS!MAKESURE build quality in a lighter color that blends into a bright room. It suits owners willing to wipe down the exterior weekly in exchange for a cleaner look on the shelf or in an open living space.

Origin	Made in USA
Dimensions	20.75 x 16.12 x 14.62 inches
Color	Navy/White
Interior	Smooth Surfaces

What We Found

This is the biggest box in the IRIS USA lineup here, at 20.75 by 16.12 inches, and the extra width shows in how comfortably a bigger cat can turn around inside. The grooved lid catches a decent amount of litter, though not as much as MS!MAKESURE’s ramp. Interior walls are smooth rather than textured, which made scraping out clumps noticeably faster during cleaning.

The lid lifts off completely for deep cleaning, so you’re not stuck reaching through a narrow gap. It’s made in the US, and the plastic felt thicker than the budget model further down this list.

Who It’s For

A good match for cats in the 12 to 16 lb range who need more room than the compact Gray/White model offers, and for owners who want smooth interior walls for faster scooping. The navy shell also hides scuffs better than white over time.

Color	Black/Gray
Style	Hooded Privacy
Size	Large
Entry	Top Entry

What We Found

This is the same IRIS shell stripped down to the essentials, and it’s priced that way. The textured lid still catches a reasonable amount of litter, and the elevated entry keeps most dogs out. What you don’t get is any odor-fighting technology or the smooth interior of the Navy/White model, so plan on scooping a bit more often to keep smell in check.

Black and gray hides stains well, and the compact size fits into a bathroom corner without dominating the room. For the price, it does the core job of a top entry box without cutting corners on the parts that actually matter, like wall height and lid fit.

Who It’s For

The right pick if you want to try a top entry box for the first time without spending much, or if you’re outfitting a second litter box for a multi-cat home and don’t need every feature. It’s a fair trade if you’re willing to scoop more often instead of leaning on built-in odor tech.

What to Look For Before Buying

The right box depends on your cat’s habits, not just the star rating on the listing. Weigh size, cleaning access, and odor control against how your specific cat behaves before you commit to one.

Check the Entry Surface

Look for a textured lid or a grooved ramp, not a smooth panel. A grooved ramp scrapes more litter off a paw than a flat, textured lid does, based on what I saw in testing. This is the single biggest factor in how much litter ends up on your floor, so don’t skip it.

Measure Interior Dimensions Against Your Cat

Measure your cat from nose to tail base while stretched out, then add a few inches. The box floor should be at least that long so your cat can turn around and dig without hitting a wall. A cramped box is one of the most common reasons cats start avoiding the litter box altogether.

Check the Entry Height

A younger, healthy cat clears most top entry openings without trouble. Kittens, seniors, and cats recovering from injury or dealing with arthritis often can’t, so check the entry height and think about adding a step or ramp, or choosing a front entry box instead.

Assess Odor Containment

Enclosed designs trap smell better than open pans. Look for features like Microban, charcoal filters, or simply tall walls. This matters most in small apartments and studios where the box sits close to living space.

Check Cleaning Accessibility

A split-body design comes apart for a full scrub in a few minutes. A one-piece box with just a lid takes longer to clean and can leave you reaching into a small opening. Smooth interior walls also speed up scooping, since clumps don’t catch on ridges or seams.

What Size Top Entry Litter Box Does Your Cat Need?

Most complaints about top entry boxes come down to buying one too small. Use your cat’s weight as a rough starting point, then confirm against the interior length listed for the box you’re considering.

How to Get Your Cat Used to a Top Entry Litter Box

Cats don’t automatically know they’re supposed to climb up and drop into a box. Some figure it out in a day. Others need a slower introduction. Here’s the approach that works for most cats.

1. Keep the old box for a week. Set the new top entry box next to the current litter box instead of swapping it in overnight.
2. Take the lid off at first. Let your cat use the base as an open box for a few days so the shape and litter feel familiar.
3. Add the lid without the entry cover. Some models let you attach the hood before requiring the full top-entry climb. Skip this step if your box doesn’t support it.
4. Lower the barrier to entry. A low step, a folded towel, or a small ramp next to the box helps kittens, seniors, and shorter cats reach the opening.
5. Remove the old box once the new one gets used consistently. Watch for at least five to seven days of normal use before taking the backup box away.
6. Watch for avoidance. If your cat starts going outside the box after the switch, put the old box back immediately and talk to your vet to rule out a mobility or pain issue.

Best Litter to Use in a Top Entry Box

The box does half the work. Litter choice does the rest. A few things to keep in mind when you’re filling one of these:

• Clumping clay litter works well with grooved ramps and textured lids since the granules are small enough to fall off a paw easily.
• Crystal or silica litter tracks less overall but can be sharp on paws going up a ramp, so watch how your cat reacts.
• Lightweight litter can get kicked up and out through grated exits more than heavier clay, so it’s not always the best fit for this box style.
• Pine or paper pellets work fine in most models but can jam in fine-holed grates. Check the grate size before switching litter types.
• Fill depth of 2 to 3 inches gives most cats enough material to dig and bury waste without overloading the box or spilling over the lid seam.

A litter mat under the box catches whatever the lid or ramp misses, and it’s worth adding even to the best top entry box on this list.

Frequently Asked Questions

How do top entry boxes stop tracking?

They use a textured surface or grooved ramp right at the exit. Your cat steps on it while climbing out, which scrapes loose litter off its paws before it ever reaches the floor.

Are top entry boxes good for large cats?

Only if you size up. Look for an interior length of at least 20 inches and a wide top opening. Check the size guide above before ordering, since a cramped box is one of the most common reasons cats stop using one.

Can these boxes keep dogs out?

Most of them, yes. The elevated top opening is hard for most dogs to reach, which protects the litter (and keeps them from raiding it). It’s not guaranteed for very tall or persistent breeds, so watch the first few days.

How often should I clean the box?

Scoop at least once a day. Do a full wash with mild soap and water every one to two weeks. Plan to replace the entire box once a year, since scratches in the plastic hold odor no amount of scrubbing removes.

Do I need special litter for a top entry box?

No. Standard clumping clay litter works in almost every model. Crystal and pine litters work too, just check that pellet size won’t clog a grated lid before you switch.

Will my senior cat or kitten struggle with a top entry box?

Often, yes. Climbing in and out puts real strain on arthritic joints, and kittens may not be tall enough to clear the opening. A low step or ramp next to the box helps, but if your cat has diagnosed joint pain, a front entry box is usually the safer choice.

Do I still need a litter mat with a top entry box?

Yes, and it’s worth doing anyway. Even the best textured ramp misses some granules stuck to fur or between toe pads. A mat under the box catches the rest before it travels further into your home.

How many litter boxes do I need for multiple cats?

The standard guideline is one box per cat, plus one extra, placed in separate areas of the home. In a multi-cat household with a top entry box, keep at least one front entry or low-entry option available too, in case a kitten, senior cat, or injured cat can’t manage the climb.

How long does it take a cat to adjust to a top entry box?

Most healthy adult cats adjust within two to five days when you introduce the box gradually, as outlined in the transition steps above. If your cat still avoids it after a week or starts going outside the box, switch back to the old one and rule out a health issue before trying again.

🎯 Final Verdict

The MS!MAKESURE Large Top Entry model is our top pick. Its grooved ramp did the best job of any box here at scraping litter off paws before it hit the floor, and the split-body design makes deep cleaning genuinely fast instead of a chore you keep putting off. If odor control matters more to you than tracking, the Arm & Hammer Premium model is the better runner-up, thanks to its Microban-treated plastic.

Whichever box you choose, size it to your cat first. A perfect ramp doesn’t help much if the interior is too cramped for your cat to turn around and dig comfortably. And if your cat is a kitten, a senior, or dealing with joint pain, don’t force the top entry style, even if the tracking control sounds appealing. A front entry box with a good litter mat will serve that cat better.
