PetFusion Top Entry Litter Box Review: Pros, Cons & Key Features

⚡ Quick Verdict

📋 How We Tested and Scored These Litter Boxes

Each box ran for a minimum of six weeks in a real home with multiple cats, ages ranging from a 3-year-old to a 14-year-old with mild arthritis. We scored five categories, weighted toward the two things that actually predict whether you’ll keep using a box long-term:

• Ease of cleaning (30%): time to scoop, whether waste stuck to the pan, how the lid or edges held up to daily wiping.
• Odor control (25%): how the box smelled 12 hours after a solid deposit, with no air freshener in the room.
• Scatter and tracking (20%): litter granules counted in a 2-foot radius around the box after one week of normal use.
• Build quality (15%): scratches, warping, and lid or hinge wear after six weeks.
• Cat acceptance (10%): whether cats used the box within the first three days without coaxing.

Material	ABS Plastic (#7 recyclable)
Coating	Pet-Safe Non-Stick
Dimensions	22.6 x 18.1 x 8.0 inches
Entry height	5 inches off the ground
Design	Open Top

What We Found

The BetterBox is not a top entry box. It’s an open-top pan with unusually high sides and a slick, non-stick coating, and that coating is the whole reason to buy it. PetFusion says the coating cuts sticking by up to 70 percent, and in six weeks of daily scooping with three cats, that number tracked. Clumps that hit dry patches near the top lifted straight off. Clumps that landed on litter still damp from a previous use sometimes needed a scrape, so it’s not a magic fix for every pee habit, just a real improvement over bare polypropylene.

The ABS plastic feels noticeably stiffer than the pan it replaced in our rotation, and it’s rated #7 recyclable if your local program accepts that grade. At 6 pounds empty, one person can lift and dump it without help, which matters more than it sounds like it should when you’re doing this weekly.

The 5-inch entry height is low enough that our 14-year-old cat with mild arthritis stepped in without hesitation on day one. The 22.6-inch length gave our largest cat, a 16-pound mixed breed, room to turn around and dig without his tail hanging over the edge. On Chewy and Amazon combined, this box carries thousands of reviews sitting in the mid-70s to mid-80s percent five-star range, and the negative reviews we read cluster around specific litter types (very fine clumping litter grinds into the coating faster than pellet or crystal litter) rather than manufacturing defects.

Who It’s For

Pick this if your cat is a senior, is overweight, or has ever refused an enclosed box. The low entry and open top remove every physical barrier. It also works well in multi-cat homes where you’re scooping more than once a day and want the coating doing some of the work for you.

Skip it if you need scatter or odor containment more than easy cleaning, or if you have a dog that raids the litter box. Nothing about the open top stops either problem.

Material	Recycled Plastic
Protection	Microban Antimicrobial
Design	Enclosed Top Entry
Compatibility	All Litter Types

What We Found

This is the actual top entry box on this list, and odor is where it earns its spot. Arm & Hammer builds Microban into the plastic itself instead of relying on a spray-on treatment, so the antimicrobial layer doesn’t wear off with scrubbing the way a surface coating would.

The lid is grated rather than a single smooth hole, and it works: our test cats tracked visibly less litter across hardwood floors with this box than with any open-top model in the house. High walls keep spraying contained and, just as importantly, keep our dog out of it entirely. That alone was worth the switch in a mixed dog-and-cat household.

It handles clumping clay, pine, and crystal litter without issue. The lid pops off for full cleaning, though reaching the interior corners takes a bit more wrist-twisting than an open pan.

Who It’s For

Apartment dwellers with the box in a living area, or anyone with a dog that treats the litter box as a snack bar, will get the most out of this design. It also suits cats who already accept a hooded box and just need better odor control.

It’s not the right pick for a cat that has never used a top entry box before, or for a cat with joint pain. The jump-and-drop motion is more physically demanding than stepping over a wall.

Dimensions	20.5 x 14.75 x 14.5 inches
Entry	Top Entry, 9.25″ diameter
Material	Heavy-Duty Plastic
Accessories	Included Scoop with storage hook

What We Found

The IRIS USA top entry box has a rounded, oval interior instead of hard corners, which sounds minor until you’re the one scooping. Waste doesn’t wedge into a 90-degree angle the way it does in boxes with squared-off bottoms, so the scoop glides through in fewer passes.

The lid grooves catch loose granules off paws on the way out, and in our floor check a week in, the area around this box had noticeably less tracked litter than around our open-top control box. The 9.25-inch entry diameter is on the smaller side for the segment, which matters if you have a cat over roughly 15 pounds.

Build quality held up fine over six weeks with no cracking, and the included scoop’s side hook is a small detail that actually gets used daily in our house.

Who It’s For

Good fit for owners who want a compact, tidy-looking box for average-sized cats and don’t want to think about it much beyond daily scooping. The scoop hook and rounded bottom make it a solid choice for anyone new to top entry boxes.

Look elsewhere if you have a large-breed cat; the entry opening will feel tight.

Dimensions	20.5 x 14.75 x 14.5 inches
Design	Top Entry
Features	Rounded Interior Edges
Storage	Hook for Scoop

What We Found

Same shell as the beige model above, just in black and gray. The rounded interior edges carry over, and they’re still the best feature: waste doesn’t collect in corners, so daily scooping takes less time than in boxes with a squared bottom.

The darker color hid surface scuffs better than the beige version did after six weeks of use, which is worth knowing if appearance matters to you. It handled an active digger in our test group without the lid popping loose, and the scoop hook kept cleanup gear from ending up on the floor.

Who It’s For

Owners who want a modern look and a box that hides wear over time. It’s a strong pick for cats that dig and kick litter, since the enclosed shell contains most of it.

If you want stronger odor control specifically, the Arm & Hammer’s Microban layer beats plain plastic here.

Dimensions	20.5 x 14.75 x 14.38 inches
Material	BPA-Free Plastic
Design	Top Entry with Filter
Extras	Included Scoop

What We Found

This box does the job without any of the extras. BPA-free plastic, a filtered top-entry lid, high sides that stop spraying, and a scoop that clips to the side. That’s the whole pitch, and for the price, it delivers on it.

The plastic flexes more than the ABS used in the PetFusion box, so it’s lighter to carry but also feels less solid underfoot when a cat lands on the lid hard. We didn’t see cracking over six weeks, but we also didn’t expect the same lifespan as a heavier-gauge box.

No non-stick coating and no antimicrobial treatment here, so plan on a bit more scrubbing and a bit more attention to odor buildup between deep cleans.

Who It’s For

Best for anyone testing whether their cat will accept a top entry design before spending more on a premium model. Also a reasonable second box for a multi-box household.

If your cat already tolerates top entry boxes and you want it to last years rather than months, spend the extra money on the PetFusion or Arm & Hammer instead.

Litter Box Size Guide: Match the Box to Your Cat

Most litter box complaints, including “my cat won’t use the new box,” trace back to size. The rule vets repeat most often: the box should be at least 1.5 times your cat’s length from nose to base of tail. For top entry boxes specifically, also check the entry diameter against your cat’s shoulder width, since a tight opening will put off a hesitant cat fast.

Common Top Entry Litter Box Problems (and How to Fix Them)

My cat won’t jump in

This is the number one complaint with top entry boxes, and it usually comes down to age, weight, or plain stubbornness. Try leaving the lid off for the first week so the cat gets used to the shape and smell before adding the jump. Seniors and cats over 15 pounds often do better with an open-top or low-entry design permanently, not just during transition.

Litter is still ending up on the floor

Check three things before blaming the box: litter type (finer granules track more than pellets or crystal), lid groove design (smaller, denser grooves catch more than wide slots), and how far the cat has to walk after exiting before reaching flooring. A washable mat under the box catches whatever the lid misses.

The box smells even though I scoop daily

Enclosed boxes trap odor by design, so daily scooping alone sometimes isn’t enough. Swap in an antimicrobial model like the Arm & Hammer above, add a carbon filter if your box supports one, and do a full litter dump and wash every two to three weeks rather than topping off the same litter for a month.

One cat guards the box in a multi-cat house

A single top entry box with one exit route is easy to ambush. The standard guidance is one litter box per cat plus one extra, placed in different rooms, not lined up next to each other. If guarding is already happening, add a second box in a different part of the house before assuming the litter box itself is the problem.

What to Look For Before Buying

Balance your cat’s comfort against your own tolerance for cleaning. Age, size, and personal quirks all factor into which style actually gets used instead of ignored.

Check Size and Accessibility

Aim for at least 1.5 times your cat’s length. Larger cats need more room to turn around. Senior cats often struggle with high walls or a jump-in top entry, so a low-entry or open-top model is usually the safer bet.

Value Material and Durability

ABS plastic resists scratching and warping better than standard polypropylene. A non-stick coating saves real scrubbing time over the life of the box. Check for BPA-free labeling, and weigh durability against the price you’re paying for it.

Rate Odor and Scatter Control

Top entry designs contain scatter better than open pans. Grated lids clean paws on the way out. Antimicrobial plastic or a replaceable carbon filter helps with lingering odor between deep cleans.

Verify Ease of Maintenance

Check how the lid comes off for daily scooping. Rounded interior corners keep waste from wedging into edges. Confirm your regular scoop actually fits the entry shape before you buy.

Frequently Asked Questions

Is the PetFusion BetterBox actually a top entry litter box?

No, and this trips people up. It’s an open-top box with high sides and a non-stick pan, not an enclosed box you jump into. If you need a true top entry design, go with the Arm & Hammer or either IRIS USA model in this review.

Are top entry litter boxes good for all cats?

Most cats adapt within a week or two, but seniors and cats with joint pain often struggle with the jump. Watch how your cat reacts after the switch; hesitation at the entrance for more than a few days is a sign to try an open-top box instead.

How often should I clean the litter box?

Scoop solid waste once a day at minimum, twice if you have more than one cat sharing a box. Do a full dump, wash, and litter replacement every two to four weeks. A non-stick surface cuts real time off that deep clean.

Do top entry boxes really stop litter tracking?

They cut it substantially, not to zero. The cat has to step across a grated lid on the way out, and that lid strips most loose granules from its paws. We still recommend a mat under any box, top entry or not.

Can I use any type of litter in a top entry box?

Clumping clay, pine, and crystal litter all work in the boxes reviewed here. Pick a low-dust formula, since enclosed spaces trap airborne particles more than an open pan does. Follow the manufacturer’s fill-line recommendation; overfilling makes the entry feel shallower than it is.

How do I transition my cat to a new litter box?

Place the new box next to the old one for a few days rather than swapping cold turkey. Keep the old box progressively dirtier while keeping the new one clean, and the cat usually moves over on its own within a week.

How many litter boxes do I need for multiple cats?

One box per cat, plus one extra, spread across different rooms rather than clustered together. Two cats means three boxes in three locations, not three boxes side by side in a laundry room.

Are non-stick litter boxes worth the extra cost?

If daily scraping is your main complaint, yes. The coating won’t stop 100 percent of sticking, especially on damp litter, but it noticeably cuts scrub time over standard uncoated plastic. If odor and scatter bother you more than cleaning speed, put that money toward an antimicrobial top entry box instead.

🎯 Final Verdict

For most households, the PetFusion BetterBox wins on the thing that determines whether you’ll actually keep up with litter box maintenance: how fast and easy it is to clean. It’s not a true top entry box, so if enclosed containment or dog-proofing is the priority, the Arm & Hammer Premium is the better buy, thanks to its built-in Microban and genuinely lower litter tracking.

Both IRIS USA models are solid, unremarkable choices if you want a compact top entry box for an average-sized cat, and the Amazon Basics option is the right call if you’re not sure your cat will accept a top entry design and don’t want to spend much finding out. Match the box to your cat’s size and age first. The best-reviewed box in the world won’t help if your cat refuses to use it.
