Arm & Hammer Rimmed Cat Litter Box Review: High-Sided Excellence

What Is the Arm & Hammer Rimmed Cat Litter Box?

Arm & Hammer has been a household name in odor control for decades, and they've brought that expertise into the pet aisle with this rimmed litter box. The defining feature is the tall, rolled rim that circles the entire perimeter — not just the entry side like some competitors. That full encirclement does a surprisingly effective job at keeping litter contained, even when a cat performs their dramatic pre-poop excavation ritual. The box is made from what Arm & Hammer describes as recycled materials, which earns it points if you're trying to reduce your household's plastic footprint.

The dimensions of 18.7 by 15.5 by 10.6 inches place it firmly in the XL category. For context, that's roughly the footprint of a standard baking sheet, but with significantly more depth. It sits low enough that most adult cats can step in without difficulty, yet the 10.6-inch side height is tall enough to stop even ambitious litter tosses. Arm & Hammer recommends replacing litter boxes every 12 months, and the inclusion of Microban antimicrobial protection is designed to buy you fresher days between those rotations.

Hands-On Review

I placed this box in my downstairs bathroom — tile flooring, which is merciful for testing cleanup claims. The unboxing was refreshingly straightforward: no strange plastic smell, no residue, just clean recycled plastic with a subtle texture that feels grippy enough for a cat's paws. By the second day, I had already forgotten it was a "new" box, which is the highest compliment I can pay to cat furniture.

What surprised me was how much the full rim mattered versus partial rims I'd used before. My older cat, Mochi, is a vigorous digger. With her old box, I was sweeping litter from behind the toilet at least twice a week. After three weeks with the Arm & Hammer rimmed box, I'd found exactly four stray pellets — all within a few inches of the entrance. The difference was noticeable by day three, and I stopped dreading that corner of the bathroom.

The Microban feature is harder to quantify because it's doing its work below the surface, but I noticed that even when I let the box go a bit longer between deep cleans during a busy week, the smell never turned that sour, deeply embedded ammonia note that signals bacterial buildup. It's not magic — you'll still need to scoop daily and do a full empty-and-scrub periodically — but it adds a genuine buffer. The box is also remarkably easy to wipe down. The plastic is smooth enough that waste slides off, and I haven't needed a scraper or tough brush yet.

Where I hit a limitation: my senior cat, Biscuit, who's about 13 years old and has a bit of arthritis in her hips. The 10.6-inch side height means she has to step up higher than she'd like. She manages, but there's a moment of hesitation every time, and I caught her once trying to use the rim as a step (which nearly ended in a tipped box situation). If you have an older cat or one with mobility concerns, this is worth factoring in. The solution — either a lower-entry box or a ramp of some kind — is an added cost and hassle.

Who Should Buy It?

• Multi-cat households — the high sides and generous size handle frequent use without constant maintenance anxiety
• Cat owners on hard flooring — if your floors are tile, hardwood, or laminate, the rim containment is a genuine quality-of-life improvement
• Eco-conscious shoppers — the recycled-material construction is a meaningful differentiator if sustainability matters to you
• Clumping litter users — the smooth, flat interior makes daily scooping fast and efficient

Skip this one if you have senior cats, kittens, or any cat with mobility challenges — the tall sides are a real barrier for them. In that case, look for a box with a lowered entry cut-out or a shallower profile.

Alternatives Worth Considering

If the Arm & Hammer rimmed box isn't quite right, these options are worth a look:

• Van Ness High Sided Cat Litter Pan — similar containment concept, typically available at a lower price point, though without the Microban protection or recycled-material claim
• Petmate Giant Litter Pan — offers an even larger footprint for extra-large cats or those who want maximum digging room, but lacks antimicrobial features
• Catit Hooded Cat Pan — a hooded alternative for cats who prefer privacy or if you want to reduce litter tracking, though it requires more disassembly for cleaning

FAQ

Final Verdict

After several weeks of real use, the Arm & Hammer rimmed cat litter box does exactly what it promises. The full-perimeter rim cuts down on scattered litter in a way that genuinely improves daily life, and the Microban antimicrobial layer provides real odor-fighting benefits between cleanings. The recycled-material construction is a nice bonus for environmentally conscious pet owners, and the generous dimensions comfortably accommodate most adult cats. It's not the right choice for every cat — senior and mobility-impaired felines will struggle with the tall sides — but for households dealing with enthusiastic diggers on hard floors, it's a practical, affordable upgrade. At its price point, you're getting reliable performance without paying for features you don't need.
