While most litter box problems are identified as a behavior problem, they can also be signs of an illness. Households with senior cats or those with indoor-outdoor cats are prone to specific veterinary problems. Cats suffering from urinary tract infections often develop an aversion to the litter box. Health problems linked to litter box mistakes can worsen without proper veterinary attention. No amount of behavior techniques can help a kitty with a veterinary problem, so a trip to the vet should be made as soon as possible. 

If your Gresham, OR veterinarian rules out a medical problem, start paying close attention to your pet’s behavior. During your observation period, focus on things in his immediate environment such as the daily routine of the household, litter boxes, food and water bowls, other cats, people, and even favorite hangouts. In time, you will be able to pinpoint the cause of the problem and be able to deal with it appropriately. Visit this link for more pet care information.
