General Cat Care – Litter Box
All indoor cats need a litter box, which should be placed in a quiet, accessible location. In a multi-level home, one box per floor is recommended. Avoid moving the box unless absolutely necessary, but if you must do so, move the box just a few inches per day. Keep in mind that cats won’t use a messy, smelly litter box, so scoop solid wastes out of the box at least once a day. Dump everything, wash with a mild detergent and refill at least once a week; you can do this less frequently if using clumping litter. Don’t use ammonia, deodorants or scents, especially lemon, when cleaning the litter box. If your cat will not use a litterbox, please consult with your veterinarian. Sometimes refusal to use a litter box is based on a medical condition that required treatment.
