IRIS USA Large Top Entry Cat Litter Box with Lid, Enclosed Covered, Dog Proof Design Review (2026)

Design and purpose

This IRIS USA litter box uses a top entry design rather than a front door, meaning the cat climbs in through an opening in the lid instead of walking through a side flap. The stated purpose of this layout is twofold: it keeps dogs from reaching into the pan since most dogs cannot or will not climb in from above, and it gives cats a private, enclosed space to do their business away from household foot traffic. The listing describes it as suited to multi-cat households as well as single-cat apartments, and it comes in a black and gray colorway with dimensions of roughly 20.5 by 14.75 by 14.38 inches.

Litter containment and the lid

The tall walls built into the enclosed shape are meant to contain both litter and any spraying inside the box rather than letting it scatter onto the floor, which matters in an apartment where the litter box often sits close to living space. The lid itself is grooved so it doubles as a litter-catching mat, meant to knock loose litter off a cat's paws as it exits through the top opening before it gets tracked across the apartment. This two-part design, tall walls plus a catching lid, is the core selling point over a standard open pan, and it is the main reason the product markets itself around tracking reduction rather than just containment.

Cleaning and materials

The box is made of durable plastic and includes a scoop that hooks onto the body of the unit for storage, so it stays with the box rather than getting lost elsewhere in the apartment. Rounded interior edges are meant to keep litter from sticking to corners, which makes scooping and full cleanouts less of a chore than boxes with sharp interior seams. Because the entire lid needs to come off to reach the top opening, a full scoop session means lifting the lid away rather than just reaching in through a front flap, which is a small extra step compared to open or front-entry designs but is the tradeoff for the added privacy and dog-proofing.

Who might struggle with the top entry

A top entry box asks more of a cat physically than an open pan or front-door box, since the cat has to jump up and climb down into the opening rather than walking straight in. This can be a real limitation for older cats with joint stiffness, very small kittens still learning to use a litter box, or overweight cats that have trouble jumping. Apartment owners with a senior or arthritic cat should weigh this against the dog-proofing benefit, since the top entry is the same feature doing double duty as both a plus and a minus depending on the cat's mobility.

Value for apartment renters

For a household with both a cat and a dog sharing limited square footage, this box solves a specific problem that open litter boxes cannot: keeping a dog out of the litter without needing a separate closed-off room. The included scoop and litter-catching lid add convenience without pushing the price toward the self-cleaning or automatic litter box category, keeping it in reach for renters on a budget. As long as the household's cat can comfortably jump and climb, this is a straightforward, no-frills way to get enclosed, tracking-reduced litter management in a shared apartment.
