What kind of litter can I use?
You can use any type of litter, but we strongly advise against clay-based or scented options. These can be harmful to for cats to breathe in and pose a significant risk to the environment.

Why Cat Parents Are Ditching Plastic for Good
Why Cat Parents Are Ditching Plastic for Good

Odor & Germ Resistant
Stainless steel is naturally resistant to bacteria and odor absorption, unlike porous plastic that traps smells. This ensures a cleaner environment for both you and your cat.
Plus, the built-in active carbon slot further neutralizes odors, keeping your home even fresher and more hygienic.

Easy to Clean
Cleaning the litter box used to mean scrubbing, soaking, and still not feeling like it was really clean.
Not anymore. Waste and clumps slide right off the stainless steel surface — no scraping, no residue.
A quick rinse and you're done in under a minute. The kind of clean you can actually see and feel, every single time.

Purrfect for Large Cats
If your cat has ever done their business half-hanging over the edge of a too-small box, you know the problem.
At 23" × 12" with high side walls, the Cattasaurus gives even large and senior cats the space to turn around, dig, and settle in comfortably — while keeping litter and mess exactly where it belongs.
Big cat, small mess.

Unmatched Durability
The average plastic litter box lasts 1–2 years before it warps, stains, and starts holding odor permanently — at which point you throw it away and buy another one.
The Cattasaurus is a different kind of investment.
Stainless steel doesn't warp, crack, or degrade. It survives aggressive cleaning, heavy daily use, and years of claws. Buy it once.
Never buy another litter box again.

Eco-Friendly & Sustainable
The average cat owner throws away 4–5 plastic litter boxes over their cat's lifetime — each one ending up in a landfill, where plastic takes hundreds of years to break down.
One Cattasaurus replaces all of them. Stainless steel is fully recyclable, built to last decades, and produces zero plastic waste.
It's the obvious choice if you care about your home, your cat, and what you leave behind.
Odor & Germ Resistant
You shouldn't have to hold your breath walking past the litter box.
Unlike plastic — which is full of microscopic pores that soak up bacteria and odor over time — our 304 stainless steel has nowhere for smells to hide.
Waste sits on the surface, not in it.

Real Reviews From Real Cat Homes


"We've had two of these for 3+ years and still going strong! So easy to clean. These are still my favorite boxes. We dump the box monthly, and scoop a few times a week. No stinky smells (unless it's a fresh poop), no sticking, ezpz."
KATIED - (verified customer)
"This box is obviously heavier due to material and the fact that it holds more litter than a standard box. But the cleanup and lack of sticking definitely makes it worth the money. Cats took to it immediately, there has only been one incident of peeing over the side in the four months we've had it."
CHARLOTTE - (verified customer)
"Great for replacing plastic litter boxes which hold the smell. Stainless does not!!! I clean the litter box every 2-3 days and there is no lingering smell you get with plastics litter boxes. The only odor you would naturally get is when the waste is not cleaned as it is with any litter box. But once cleaned NO odor lingers. Highly recommend!!"
