IRIS USA Large Top Entry Cat Litter Box with Lid, Enclosed Covered, Dog Proof, Odor Control, Scoop Included, White/Beige Review (2026)

Top entry and dog-proofing

Like other boxes in IRIS USA's top entry line, this model has a cat enter through an opening in the lid rather than a front-facing door, with tall walls extending well above the litter line on every side. That height difference is the main reason these boxes are marketed as dog proof: most dogs cannot easily reach far enough into a narrow top opening to disturb the litter or reach waste the way they could with an open pan or a low front-entry box. For apartment households where a cat's litter box and a dog's living space cannot be kept in fully separate rooms, that physical barrier is often more reliable than trying to train a dog to leave the box alone.

Dimensions and capacity

This large size box measures roughly 20.5 inches long, 14.75 inches wide, and about 14.4 inches tall on the outside, with an entry opening around 9.25 inches in diameter and an interior floor space of about 17 by 11.5 inches. Those measurements put it toward the larger end of top entry boxes, giving bigger cats more room to turn around and dig, and giving multi-cat households more litter capacity without needing multiple boxes. The enclosed shape means the box holds more litter within the same footprint than a similarly sized open pan, which can reduce how often the litter needs topping off between full changes.

Color and where it fits visually

This version comes in white and beige rather than the gray and white or black and gray combinations IRIS USA sells elsewhere in the same line, which tends to blend in more easily with light bathroom tile, cream-colored walls, or neutral apartment decor than a darker box would. The tradeoff of a lighter color scheme is visibility of dust and stains: litter dust, paw prints, and general grime show up more noticeably against white and beige plastic than they would against gray or black, so this option will likely need more frequent wiping down to keep looking clean compared with a darker-colored box from the same lineup.

Scoop and odor control

A scoop is included with this listing, so it is ready for daily use out of the box without a separate purchase. IRIS USA markets the enclosed top entry shape as helping with odor control, since the tall walls and lid contain smell more than an open pan does, though like any enclosed box it still needs regular scooping to prevent odor from building up inside the confined space. The lid's grooved surface is designed to catch litter from a cat's paws as it exits through the top, reducing tracked litter around the box, a feature shared across IRIS USA's top entry models rather than unique to this color version.

Who should buy it

This box suits an apartment household with an adult cat and a dog that needs to be kept away from the litter box, and who wants a lighter color scheme that blends into bathroom or hallway decor. It carries the same physical demands as other top entry boxes, so it is not the right pick for senior cats, cats with joint issues, or young kittens that may struggle to jump up and through the top opening. Owners who want to minimize visible dust and grime with less frequent wiping may prefer a darker-colored box from the same IRIS USA lineup instead of this white and beige version.
