1 / 7IRIS USA 589628 Top-Entry Cat Litter Box, Large
IRIS USA 589628 is a large, covered top-entry litter box with a textured lid intended to catch loose litter as cats exit. Its enclosed layout may suit homes seeking added privacy and a barrier to curious dogs, but top access is a poor fit for cats that will not use it.
At a glance
- Top entry and an enclosed body provide a more private litter area.
- Textured lid is designed to catch loose litter from paws and direct it back into the box.
- Manufacturer describes the elevated entry as a way to make dog access more difficult, not an absolute barrier.
- Rounded body and lid hook are described as supporting access for cleaning. The box also has a molded hook for the included scoop.

Customer feedback highlights reported ease of use, cleaning and litter containment, with some customers saying cats adapt quickly and the box works in multi-cat homes. Others report that their cats will not use it, so top-entry acceptance is a meaningful fit question. Ratings skew strongly positive overall, but ratings alone do not explain individual experiences or establish how well it will suit a particular cat.

- Customers describe effective litter containment and use in multi-cat homes.
Negative themes
- Some customers report that their cats will not use the box.
Mixed feedback
- Reports about pet compatibility vary. Some find it keeps dogs away, while others say their cats reject the top-entry design.
Frequently asked questions
Does this litter box include a scoop?
Yes. The listed components include a cat litter container, scoop and lid, and the product details identify the color as “Black w/ Scoop.”
How large is the box?
The listing calls it Large, but dimension formats conflict. It gives 20.5"L x 14.75"W x 14.38"H in one place and 20.5 x 14.75 x 14.38 inches; 2.78 pounds in another. Confirm the dimensions before buying.
Will it keep dogs out of the litter?
The elevated top-entry design is described as making access difficult for dogs. That is a claimed deterrent, not a guarantee.
Will every cat use a top-entry box?
No. Customer feedback is mixed on cat acceptance, with some reports that cats will not use it. Consider your cat’s comfort with climbing into the box.
