Cat Litter Box Problems (cont.)
If Your Cat Is Unable to Use Her Litter Box
Special-needs cats such as those who are older, arthritic or still very young might have trouble with certain types of litter boxes. Boxes that have sides that are too high or have a top-side opening might make it difficult for your cat to enter or leave the box. Try switching to a litter box with low sides.
As in any situation where the cat may have eliminated outside her box, clean accidents thoroughly with an enzymatic cleanser designed to neutralize pet odors. You can find this kind of cleaner at most pet stores.
Treatment for Negative Litter-Box Association
If your cat has experienced some kind of frightening or upsetting event while using her litter box, she could associate that event with the litter box and avoid going near it. Things that might upset your cat while she's eliminating in her box include being cornered or trapped by a dog, cat or person, hearing a loud noise or commotion, or seeing something frightening or startling. These experiences-or any other disturbing experience-could make your cat very reluctant to enter her litter box. If your cat is afraid of her litter box, you may notice her running into the box and then leaving again very quickly, sometimes before she's finished eliminating. You may also notice her eliminating nearby, but not inside her box. This means that your cat is worried about using her box, especially if she has reliably used litter box in the past.
