Amazon Basics Top Entry Litter Box Review: Pros, Cons & Features

⚡ Quick Verdict

📋 How We Evaluated

I scored each box on four things: scatter control (how much litter ends up on the floor after a normal week of use), odor containment, ease of cleaning, and how the plastic held up under daily scooping. A box with high sides and a small entry point scores well on scatter but loses points if the lid makes deep cleaning a chore.

Top Entry vs. Open Top Litter Box: Which One Fits Your Cat?

This is the real decision buried inside every “top entry litter box review.” Both styles in this roundup share the same tall walls and roughly the same footprint. The difference is where your cat gets in.

A top-entry box makes your cat climb up and drop in through an opening in the lid. That climb does two things. It knocks loose litter off their paws before they’re back on your floor, and it keeps the digging and spraying contained inside four walls instead of one open side. The tradeoff is mobility. A cat has to jump, and a senior cat, an overweight cat, or a kitten still learning to climb may avoid the box entirely rather than struggle with the entry.

An open-top box with high sides, like the Amazon Basics Open Top model in this review, keeps three of those four walls but drops the roof and lowers the front. Your cat steps in instead of climbing. You lose some of the paw-scrubbing effect of a lid, so expect slightly more tracking, but you gain easy access and effortless monitoring, since you can see litter level and clumps at a glance without lifting anything.

If your cat is young, healthy, and already uses a covered box without hesitation, go top entry. If you’ve got a senior cat, a kitten, a large breed, or any cat with joint issues, the open-top model or a low-entry box is the safer call.

Dimensions	20.5 x 14.75 x 14.38 inches
Material	BPA-free plastic
Type	Top Entry
Includes	Matching scoop

What We Found

The Amazon Basics Large Cat Litter Box leans on a top-entry design to keep mess where it belongs. The high walls hold scattered litter in, and the enclosed shape gives a cat somewhere private to go. The BPA-free plastic doesn’t feel cheap. Mine has taken four months of daily scooping without a crack or a stress mark near the lid hinge.

The built-in scoop storage is the detail that sold me. It clips to the side, so the scoop is never buried under a towel or lost behind the washer. Pop the lid off and you get a clear view of the whole pan for a real cleaning, not just a scoop-and-go.

Room inside is generous for an average-sized cat. My 11-pound tabby turns around and digs without her tail brushing the walls. The grey finish is plain in a good way. It disappears into a laundry room or bathroom instead of announcing itself.

Who It’s For

Good fit for anyone sick of finding litter granules three feet from the box, or anyone in a small apartment who needs the box to look tidy from across the room. Cats that already like privacy adjust to it fast. It also works well when you need to keep a dog or a second, nosier cat out of the litter entirely.

If you’re currently juggling a separate scoop holder, this solves that problem on its own.

Dimensions	20.5 x 14.75 x 14.38 inches
Entry diameter	Approx. 9.25 inches
Protection	Dog-proof entry height
Color	Gray/White

What We Found

The IRIS USA top-entry box wins on one specific thing: the grooved, textured lid. It scrapes litter off paws on the way out, and it works. I noticed fewer stray granules by the door within the first week compared to a plain flat-lid box. The enclosed shape also keeps odor from spreading the way an open pan does.

Build quality is solid, and IRIS lists this line as made in the USA with globally sourced materials. The plastic resists staining better than I expected after weeks with clumping litter. Gray and white keep it from standing out in a hallway or utility room.

If tracking is your main complaint about your current box, this is the one in the lineup built specifically to fix it.

Who It’s For

Best for owners dealing with litter on hardwood or carpet no matter what they try. It also works as a deterrent for a curious dog, since the entry sits too high and too narrow for most breeds to bother with. Anyone who wants the box hidden but still tidy-looking will like the finish.

Dimensions	20.5 x 14.75 x 14.38 inches
Color	Black/Gray
Type	Hooded privacy
Benefit	Reduces litter tracking

What We Found

Same box as the gray IRIS USA model above, just in black and gray. Same grooved lid for tracking control, same enclosed shape for privacy and odor control. If you want something that reads as industrial or modern instead of soft and neutral, this is the color to grab.

It contains scatter just as well as its sibling and the plastic handles regular scooping without showing wear after weeks of use. Like the other IRIS models here, the entry height keeps most dogs from wandering in.

It’s a consistent performer that checks every box you’d expect from a quality top-entry unit, with the only real difference from the gray version being color.

Who It’s For

Good for owners who want a darker finish that hides scuffs between deep cleans. It fits naturally in a modern or minimalist home where a black-and-gray palette already runs through the room.

Dimensions	20.5 x 14.75 x 14.38 inches
Entry Diameter	9.25 inches
Color	Beige
Construction	Made in USA

What We Found

The beige IRIS USA model gives you the same enclosed, tracking-focused design in a softer color. The lid catches loose litter before it hits your floor, and the walls are tall enough to stop spraying from reaching the outside of the box.

The scoop hangs off the side on a hook, so it stays put between cleanings instead of sliding around the bathroom floor. Beige blends into more neutral interiors than the stark white or black options, and the construction feels every bit as sturdy as the gray and black versions.

Interior space is generous enough for most cats to turn around without brushing the walls, which matters for cats that like to dig before settling.

Who It’s For

Great for owners who want a discreet, neutral-toned box that blends into existing decor. It also works well in multi-pet homes where keeping a dog away from the litter is a priority.

Dimensions	19 x 15 x 11.75 inches
Type	Open top
Material	Recyclable plastic
Special	Lowered front entry

What We Found

This is the box for a cat that hates the top-entry style. High sides still do the job of trapping most scatter, but the lowered front entrance means there’s no jump required. That matters for older cats and anyone with joint pain.

The BPA-free plastic wipes clean fast, and the scoop that comes with it is basic but functional. Without a lid, checking litter level takes a glance instead of a lift. It’s a no-frills box that does what it says and nothing more.

It’s also light enough to carry outside for a full rinse, which the heavier hooded models aren’t.

Who It’s For

Best for senior cats, cats that feel boxed in by a hood, or owners who want to scoop several times a day without lifting a lid each time.

How to Transition Your Cat to a Top-Entry Litter Box

Cats don’t automatically know what to do with a lid over their heads. Switch too fast and you risk a cat refusing the box altogether, which usually means an accident somewhere you don’t want it. Give the switch a week and most cats adjust without any drama.

1. Place it next to the old box first. Don’t swap locations and box styles at the same time.
2. Leave the lid off for two to three days. Let your cat use it like an open box while it gets used to the new shape and smell.
3. Add the lid but prop the entry hole open wider if possible. Some cats climb in fine right away; others need the opening to feel less tight at first.
4. Remove the old box only after you see consistent, confident use of the new one. That’s usually five to seven days in, not day one.
5. Watch for hesitation at the entry. A cat that paces around the box without going in for more than a day may need a ramp, a step stool nearby, or a switch to an open-top design instead.

Kittens under six months and cats recovering from surgery or arthritis flare-ups often do better skipping the top-entry style entirely. There’s no shame in going with an open-top box like the one at the bottom of this list if the climb becomes the obstacle instead of the litter.

Best Litter to Use With a Top-Entry Box

The box handles half the tracking problem. The litter you pour into it handles the other half.

• Clumping clay litter works well in these boxes because it forms tight clumps that scoop clean and don’t crumble into dust that clings to paws.
• Skip lightweight crystal litter if tracking is your main complaint. It’s easier to carry out on paws and shows up on the lid grooves and the floor around the box.
• Fill to about two to three inches. Too little and your cat digs straight to the plastic; too much and extra litter rides out on the climb through the top entry.
• Unscented is safer for sensitive cats. A strong perfume in the litter can put a cat off the box entirely, which defeats the point of any upgrade.

What to Look For Before Buying

Picking the right box comes down to matching the design to your cat, not to what looks best in a photo. Weigh your cat’s age and mobility before you commit to a top-entry or open-front design, and don’t skimp on plastic quality if you want the box to survive years of daily scooping.

Check Entry Style and Accessibility

Top-entry boxes control scatter well, but they ask your cat to jump. Make sure your cat is healthy enough to climb in and out without hesitation. Older cats usually do better with an open, low-entry design. Put your cat’s mobility ahead of how tidy the closed box looks.

Value Size and Footprint

Measure the spot where the box will live before you buy. The interior needs to be roomy enough for your cat to turn a full circle. A cramped box discourages use and leads to accidents outside it. Weigh the outer dimensions against how much interior space actually stays free once litter goes in.

Rating Durability and Materials

Stick with BPA-free plastic that resists scratching, since scratches trap odor and bacteria over time. Smooth interior walls wipe down faster during your weekly clean. Avoid anything that flexes noticeably under the weight of a full litter load; a sturdy base keeps the box from tipping when a cat jumps in hard.

Check Weight Capacity for Large Cats

Most boxes in this size range hold around 20 to 25 pounds of litter, which is plenty for a typical cat, but a large-breed cat needs to check the entry diameter too. A 9-inch opening is fine for most cats; a Maine Coon or a larger mixed breed may find it tight, which pushes some owners toward the open-top model instead.

Plan for Multi-Cat Households

The standard rule from vets is one litter box per cat, plus one extra. Two cats means three boxes, spread across different rooms rather than lined up side by side. A top-entry box works fine as part of that setup, but don’t rely on a single hooded box to cover a two- or three-cat household. Cats guard territory, and a shared box can turn into a source of stress rather than a solution.

Verify Maintenance Features

Look at how easily the box breaks down for a deep clean. Built-in scoop storage saves you a daily search. A removable lid makes it simple to check litter levels without guessing. Pick a design that shortens your daily chore instead of adding a step to it.

Litter Box Maintenance Checklist

A good box only stays good if you keep up with it. Here’s the routine that keeps a top-entry model working the way it should.

• ☑ Scoop clumps and waste at least once a day.
• ☑ Wipe the lid grooves or textured surface weekly so they don’t cake up.
• ☑ Empty and wash the whole box with mild soap and water every two to four weeks.
• ☑ Check the entry hole and lid seams for cracks every few months.
• ☑ Replace the box entirely once odor sets into the plastic and won’t wash out, usually around the one- to two-year mark with daily use.
• ☑ Keep a litter mat under the entry side to catch anything the lid misses.

Frequently Asked Questions

Are top-entry litter boxes better than regular ones?

For scatter control and keeping dogs out, yes. For older cats or cats with mobility issues, no, since the climb can be enough to stop them from using the box. Match the design to your specific cat instead of assuming one style wins across the board.

How often should I clean the box?

Scoop daily. Deep clean with soap and water every two to four weeks. Skipping either step is the fastest way to end up with an odor problem no amount of good litter can fix.

Do these boxes actually help with odor?

Enclosed top-entry boxes trap odor better than open pans because there’s less surface area exposed to the room. That said, no box replaces regular scooping. Pair a top-entry design with a quality clumping litter and daily maintenance for the best result.

Can my dog get into a top-entry litter box?

Most dogs can’t manage the elevated, narrow entry. It’s one of the more reliable ways to keep a dog out of the litter without a separate barrier or gate.

Will my cat actually use a top-entry box?

Most cats adjust within a week, especially cats that already like privacy. Leave the lid off for the first few days and introduce it gradually rather than swapping boxes overnight. See the transition steps above if your cat is hesitant.

Is a top-entry box good for large cats?

It depends on the entry diameter. A roughly 9-inch opening fits most cats, but a large-breed cat like a Maine Coon may find it tight. Check the listed entry size before buying, and consider the open-top model if your cat is on the larger side.

How many litter boxes do I need for multiple cats?

One box per cat, plus one extra, placed in separate locations. A single top-entry box, however well designed, isn’t enough for a multi-cat household on its own.

How long does a plastic litter box like this last?

With daily scooping and a proper wash every few weeks, expect one to two years of solid use before odor or scratching in the plastic makes it worth replacing.

🎯 Final Verdict

For most households, the Amazon Basics Large Cat Litter Box with High Sides, Top Entry is the one to buy first. Durable plastic, real scatter control, and a scoop holder that actually keeps the scoop where you need it. It cuts daily maintenance down without asking your cat to give up privacy.

If litter tracking specifically is your problem, not just scatter but litter clinging to paws and showing up down the hall, the IRIS USA Top Entry model’s grooved lid earns its runner-up spot. And if your cat is older, oversized, or just won’t climb into anything with a roof, the Amazon Basics Open Top box solves that without giving up much scatter control. Pick based on your cat, not just the score.
