How many litter boxes do you need

The standard rule is one litter box per cat plus one extra. For a single cat, two boxes. For two cats, three boxes. This prevents one cat from monopolizing all access and gives cats options if one box is recently used. In multi-level homes, at least one box per floor is important — cats sometimes will not travel between floors to find a clean box.

Open vs covered litter boxes

Covered boxes reduce scatter and contain odor for humans. However, they trap odor inside the box where the cat has to breathe it — which some cats dislike. If your cat is avoiding a covered box, remove the hood and see if behavior improves. Very large cats may also dislike the cramped space. In general, offer a mix and let your cat tell you what they prefer.

Frequently Asked Questions

How often should a litter box be fully cleaned?
Scoop at minimum once daily — ideally twice. A full dump, wash with soap, and refill should happen every 2 to 4 weeks depending on how many cats use it. Plastic absorbs ammonia over time, so even a clean-looking box can smell. Replace the box itself every 1 to 2 years.
Why is my cat avoiding the litter box?
Common reasons: not scooped frequently enough, litter brand changed, box too small, box too enclosed, new pet or person in the house stressing the cat, or a medical issue like a UTI or crystals. If a cat that has been reliably using the box suddenly stops, a vet visit is warranted.
