Cat Litter Box Problems (cont.)

Inability to Use the Litter Box

Geriatric cats or cats with physical limitations may have a difficult time using certain types of litter boxes such as top-entry boxes, or litter boxes with high sides.

Negative Litter-Box Association

There are many reasons why a cat who has reliably used her litter box in the past starts to eliminate outside of the box. One common reason is that something happened to upset her while she was using the litter box. If this is the case with your cat, you might notice that she seems hesitant to return to the box. She may enter the box, but then leave very quickly-sometimes before even using the box.

One common cause for this is painful elimination. If your cat had a medical condition that caused her pain when she eliminated, she may have learned to associate the discomfort with using her litter box. Even if your cat's health has returned to normal, that association may still cause her to avoid her litter box.

Household Stress

Stress can cause litter-box problems. Cats can be stressed by events that their owners may not think of as traumatic. Changes in things that even indirectly affect the cat, like moving, adding new animals or family members to your household-even changing your daily routine-can make your cat feel anxious.

Multi-Cat Household Conflict

Sometimes one or more cats in a household control access to litter boxes and prevent the other cats from using them. Even if one of the cats isn't actually confronting the other cats in the litter box, any conflict between cats in a household can create enough stress to cause litter-box problems.
