The SmartCat Corner Litter Box is a one-piece triangular pan made to tuck into a corner. It may save floor space, but its lower entrance can let litter escape, and the available reviews include complaints that it is too small for some cats. Consider your cat’s size, turning room, and comfort with the entry before choosing it.
What the SmartCat Corner Litter Box is—and what its dimensions mean
Chewy describes this gray pan as durable plastic resin, with high sides and a marked fill line. The corner-shaped footprint is its main practical distinction: it can use an otherwise awkward corner, but the triangular interior may provide less room to turn than a larger rectangular pan.

Published measurements are not fully consistent. Cats.com reports 24 × 19 × 8 inches, and one Chewy Q&A response gives the same dimensions. Another Chewy Q&A response lists overall dimensions of 24 × 19 × 8.5 inches and a 5-inch entry step. Treat these as source-reported figures rather than a settled manufacturer specification; check the physical product if an exact clearance or entry height matters.

That can make the opening more accessible than the sides, but it does not establish that the step will suit every cat. Customer comments flag the entry height as a possible issue for some older or mobility-limited cats.
#1 Best Overall
- SPACE-SAVING CORNER LITTER BOX – Designed with an isosceles triangular shape, this corner litter box fits neatly against two walls to save valuable floor space. Ideal for bathrooms, playpens, apartments, small rooms, and other tight spaces where a traditional rectangular litter pan may not fit.
- 3.5-INCH LOW ENTRY LITTER BOX – The lowered front opening makes it easier for kittens around 4 weeks and older, small cats, senior cats, and cats with limited mobility to step in and out. This low entry litter box supports easier litter training and comfortable everyday use.
- SMALL LITTER BOX FOR KITTENS – Measuring 14.5 inches across the front, with two 11.8-inch sides and a total height of 5.1 inches, this compact pan is specially sized for kittens and small pets. Please measure your pet and available corner space before ordering; not intended for average or large adult cats.
- STABLE & PAW-FRIENDLY KITTEN LITTER BOX – The molded bottom pattern helps reduce sliding on smooth floors, while the rounded rim and polished edges are gentle on delicate paws. The one-piece construction contains no sharp seams, creating a comfortable kitten litter box for daily use.
- LIGHTWEIGHT, DURABLE & EASY TO CLEAN – Made from sturdy, lightweight plastic with a smooth interior that is easy to wipe or rinse clean. Its compact design makes it convenient to move, carry, or store, while Pink, Green, Blue, 2-pack, and 3-pack options provide flexible choices for multi-kitten homes.
How well does it contain litter?
High walls may help contain litter kicked toward the sides, but the open, lower entrance is a likely escape route. In Cats.com’s review, Ma’ayan Gutbezahl bought the pan and used it with her two average-sized cats for a couple of weeks. She observed litter scattered around the opening. Filling below the marked line reduced the mess but did not eliminate it. That is one reviewer’s experience, not a controlled test or a guarantee of how another cat will use the pan. (Cats.com review)
Customer feedback is mixed: some owners value the corner fit and high sides, while others report that the pan is too small or messy for their particular cats. Size, digging habits, and posture can all affect the result, so neither containment nor fit is assured. A litter-trapping mat is an optional way to catch stray litter outside the pan if tracking is your concern; the available evidence does not show that a mat will stop scatter.

Is it roomy and accessible enough for your cat?
Do not judge fit from the outside dimensions alone. A cat needs room to enter, turn around, dig, and settle into its preferred posture. The triangular shape can constrain that usable area, and reported customer complaints suggest the box does not suit every cat. If your cat is large, long-bodied, or tends to turn before toileting, compare the interior space with a pan your cat already uses successfully.
Recommended Free Tools
- Potentially suitable: a cat that comfortably fits the available floor area and can step over the reported 5-inch entry.
- Use caution: a cat with mobility limits or one that struggles with a raised step.
- Consider a roomier shape: a cat that needs more turning space or already has trouble using compact pans.
These are practical considerations, not guarantees based on a formal fit test. Cats.com’s reviewer used the box with two average-sized cats; that small, individual evaluation cannot establish suitability for cats generally.

What setup and upkeep should you expect?
The Cats.com reviewer reports that the box arrives as one piece and requires no assembly. The design does not require a liner, according to that review. Chewy describes a fill line, which provides a suggested fill depth; the Cats.com reviewer’s experience indicates that staying below it may reduce, but will not necessarily prevent, litter escaping at the opening.
Cats.com scored the box 4.1/5 overall on a review page updated October 3, 2025. Its category scores were 5/5 for ease of cleaning, 2.5/5 for odor control, 4.5/5 for appearance, 4/5 for construction, and 4.5/5 for price. Chewy’s retrieved product snapshot showed 4.5 stars from 474 ratings. These are different sources and rating systems, and customer scores do not predict how the box will work for an individual cat.

How does it compare with other corner pans?
Chewy’s recommendations include a Van Ness high-side corner box, but the available information does not establish a head-to-head test. Compare alternatives using the factors that affect your home and cat:

- Usable floor area: check space for turning, not only the pan’s outer footprint.
- Entry height: consider whether your cat can step in comfortably.
- Side height and opening: higher walls may help with kicked litter, while an open entrance can still allow scatter.
- Form and cleaning: weigh corner placement against the access and interior room of a rectangular or covered pan.
- Current price: compare listings at the time you buy; prices and availability change.
Choose based on the cat’s demonstrated needs, not a claim that one shape or wall height will contain litter for every household.
