      Litter Box Calculator FAQ

      How many litter boxes do I need for one cat?
      Most homes should have at least two litter boxes for one cat. A common rule is one litter box per cat, plus one extra.
      How many litter boxes do I need for two cats?
      For two cats, three litter boxes is usually a better setup. This helps reduce competition, stress, and accidents outside the box.
      Do I need a litter box on every floor?
      Yes, multi-level homes should usually have at least one litter box on each floor so your cat always has easy access.
      Can too few litter boxes cause peeing outside the box?
      Yes. Too few boxes can cause stress, guarding, odor buildup, and avoidance. If your cat is peeing outside the box, adding another clean box may help.
      Where should I place litter boxes?
      Place litter boxes in quiet, easy-to-reach areas. Avoid hiding them near loud appliances, food bowls, or areas where another cat can block access.
      Should litter boxes be covered or uncovered?
      Many cats prefer uncovered boxes because they feel safer and have more space. Covered boxes may trap odors and make some cats avoid using them.
