But cats do not act out of spite or revenge, so it won't help to give your cat special privileges and hope she'll start using the box again. If your cat is declawed, that is not likely to be the cause of the problem either. If stress is involved, you should see other behavioral or physical changes as well such as weight loss, fearful behavior, or changes in eating or sleeping habits. Punishment is not a way to resolve a litterbox problem. First, check with your veterinarian.
Health problems can cause litterbox problems.
Cats don't always act sick, even when they are. Only a trip to the veterinarian for a thorough physical exam, which may include a urinalysis, can rule out a medical problem. If you cat is given a clean bill of health by your veterinarian, the next step is to determine whether your cat is spraying or urinating outside the box. Spraying is urine marking behavior, and is a cat's way of indicating ownership of her territory. Marking is triggered by the presence of other cats.
