CATPAK Stainless Steel Cat Litter Box Review: Worth It?

If you are tired of scooping a litter box that still smells like urine no matter how often you clean it, the CATPAK Stainless Steel Cat Litter Box is built to solve exactly that problem. This extra-large stainless steel litter box pairs a 201 stainless steel pan with an ABS plastic cover, and it can switch between a fully enclosed box and an open litter pan depending on what your cat prefers.

I went through the CATPAK’s design, components, and real-world tradeoffs to see whether the stainless steel upgrade is worth its $108.99 price. The short version: the odor control and flexibility are genuinely good, but the 201-grade steel and the sheer size mean it is not the right litter box for every home.

What I Liked About the CATPAK Stainless Steel Cat Litter Box

Stainless Steel That Resists Odor

The main reason to pick a stainless steel litter box over a plastic one is odor, and the CATPAK delivers here. The 201 stainless steel pan is smooth and non-absorbent, so urine and feces sit on the surface instead of soaking into the material the way they do with a scratched plastic litter box.

Reddit owners who switched from plastic echo this repeatedly, with one r/cats user saying the difference in odor control was incredible after moving to steel. As long as you rinse the pan while scooping, it does not hold onto that lingering ammonia pee smell between deep cleans.

Extra-Large Pan for Big and Multi-Cat Homes

This is a big litter box. The stainless steel pan measures about 22.8 by 16.5 by 5.9 inches and holds roughly 20 lbs of litter, giving even a big cat up to 25 lbs room to turn around and dig.

That capacity also stretches cleaning intervals. CATPAK estimates the litter lasts up to 30 days for one cat or 15 days for two, so it suits a Maine Coon-sized cat or a multi-cat household that would overwhelm a standard pan.

Convertible Covered Box or Open Litter Pan

Cats can be picky about their litter box, and the CATPAK gives you options instead of forcing one layout. You can run it as a covered box with the ABS lid on, or lift the entire top off to leave an open stainless steel litter pan.

Entry is just as flexible. There is a top flap, a liftable lid with two locks, and a front door you can lock in place or remove entirely for a low, open entry that older cats find easier.

One-Click Disassembly and Easy Cleaning

Cleaning a litter box is nobody’s favorite chore, and the CATPAK’s one-click disassembly makes it less of one. You press the marked buttons on both sides, hear a click, and lift the cover off without tools, which the lone Amazon reviewer called simple enough for their young son to manage.

Because the pan is smooth stainless steel, clumps lift cleanly and the surface wipes down fast. There are no scratched-in grooves for waste to stick to, so a deep clean is closer to a rinse than a scrub.

Complete Kit With Scoop and Litter Mat

The CATPAK arrives as a full set rather than just a pan. In the box you get the stainless steel litter box, a removable cover, a heavy-duty sifting scoop with a hook, a double-layer honeycomb litter mat, and an odor pad for the lid.

Two honeycomb grids, one on the front step and one on the pedal rest, knock stray litter off your cat’s paws before it hits the floor. The sifting scoop lets you sift out clumps quickly, and its side holder keeps it within reach of the box.

What Needs Improvement

201-Grade Steel, Not 304

The CATPAK’s pan is 201-grade stainless steel, not the food-grade 304 that higher-end boxes use. Industry write-ups like Huckwell’s note that 201-grade steel is cheaper and more porous, and can begin to corrode and trap odor within one to two years of constant ammonia exposure if you do not deep clean it regularly.

In practice that means the odor advantage over a plastic litter box is real but not permanent unless you stay on top of maintenance. Buyers expecting a decade of service from 304-grade steel should read the material spec closely. Owners who would rather automate that upkeep entirely can look at the Robotail Open Top Litter Box, which self-cleans after every use for multi-cat households.

Heavy and Large-Footprint

All that steel and space comes with bulk. The unit weighs about 4.8 kg (10.6 lbs) empty, and once it holds 20 lbs of litter, sliding it out to clean takes real effort compared with a lightweight plastic box.

Its footprint is just as demanding. At nearly 23 inches long, this litter box eats floor space, so it is a poor fit for a small apartment or a tucked-away corner. For a studio apartment or a small cat that cannot spare that space, the AIPERRO Stainless Steel Litter Box delivers the same non-porous steel in a compact footprint.

Not Built for Kittens or Small Cats

The CATPAK is sized for cats roughly 15 to 25 lbs, and that focus shows. In the demo video, the reviewer states outright that it is not for cats under 15 lbs, and the tall sides can make entry awkward for kittens.

One retail reviewer even found the metal held a kitten’s stronger waste odor more than expected, suggesting it suits adult cats better. A tiny kitten or a senior with mobility issues may do better with a lower-sided pan.

Higher Price and a Thin Track Record

At $108.99, the CATPAK costs two to three times what a basic plastic litter box does, and roughly double a simple stainless pan like Frisco’s. That is a lot to pay for a brand with a thin review history.

As of this review the Amazon listing carries a single rating, so there is little long-term feedback on how the seams, locks, and 201 steel hold up. Owners who want proven reliability may prefer a more established stainless steel litter box. The brand’s own Natural Attapulgite Clumping Cat Litter is another young CATPAK product, a low-dust unscented option suited to single-cat and two-cat homes. If the CATPAK’s price feels steep for one piece of a cat’s setup, a budget grooming pickup like the aumuca Undercoat Rake covers deshedding for long-haired breeds at under $20.

How the CATPAK Compares to Other Stainless Steel Litter Boxes

The most direct budget alternative is the Frisco Stainless Steel Cat Litter Box, which reviewers name a best-value pick at just under $40. It is a simple open pan, though, with no cover, no door, and none of the CATPAK’s accessories, so you trade flexibility and enclosure for a much lower price.

Step up in price and the iPrimio Stainless Steel XL is the enthusiast favorite for durability and odor control. It is a high-sided open tray rather than a convertible enclosed box, so it suits owners who never wanted a lid in the first place.

The Meowant Stainless Steel LB02 is another common recommendation as a default stainless choice, sitting between Frisco and iPrimio on price. Against these, the CATPAK’s pitch is the convertible cover, the extra-large pan, and the bundled scoop and mat.

If you are cross-shopping enclosed plastic designs like the Modkat Flip or a Catit hooded box, remember the core tradeoff. Those plastic litter boxes offer more shapes and colors, but plastic litter traps odor as it scratches, which is the exact problem the CATPAK’s steel is meant to avoid.

Final Verdict

The CATPAK Stainless Steel Cat Litter Box earns a 4.6 out of 5. As a large, convertible litter box, it nails the two things buyers move to steel for: strong odor control and a smooth pan that stays clean with minimal scrubbing.

Its limits are just as clear. The 201-grade steel needs regular deep cleaning to keep its odor edge, the box is heavy and space-hungry, and it is more than a kitten or a cat under 15 lbs needs.

For a single big cat or a multi-cat household tired of replacing smelly plastic litter boxes, the CATPAK is worth the $108.99. If you have small cats, limited floor space, or want proven 304-grade longevity, a different stainless steel litter box will serve you better.
