Do Vets Recommend Enclosed Litter Boxes? What to Know

Veterinarians do not generally recommend an enclosed litter box for every cat. A covered box can work if your cat uses it comfortably and you keep it clean, but an uncovered box is often the easier starting point because it offers more space, airflow, and visibility. If you are deciding between styles, start with your cat’s habits rather than the box’s appearance.

Your cat should be able to enter, turn around, dig, and leave without brushing against the walls or lid. Choose a box at least one and a half times your cat’s body length, measured from nose to the base of the tail. For kittens, senior cats, or cats with mobility issues, a low entry may matter more than a cover.

A lid may help contain scattered litter and give your cat a more secluded place to go. It can also trap odors inside, even when the area around the box smells clean to you. Scoop at least daily, and remove the lid if your cat hesitates at the entrance or starts avoiding the box.

For multiple cats, provide more than one litter box in separate locations so access does not depend on sharing a single enclosed space. Our team favors roomy boxes with simple surfaces you can clean thoroughly, whether they have a removable cover or no cover at all.
