Every cat needs a litter box, but the “best” one really depends on your cat and your space. This is an editor’s shortlist across the main box types — not a lab test — so you can match the right style to your home instead of guessing.

How to choose
Two rules cover most homes. First, the common guideline is one box per cat, plus one extra — so two cats means three boxes. Second, size beats style: a box should be about one-and-a-half times your cat’s length so they can turn around comfortably. Kittens and older cats need a low entry, so skip top-entry boxes for them. Wherever you put it, keep the box away from food and water.
