Dealing with a cat who pees outside the litter box is one of the most frustrating issues cat guardians may be faced with. It’s also one of the most common reasons why cats are returned to shelters. The reasons why cats eliminate outside the litter box vary, and include litter box aversion, urine marking, hormonal problems, and medical issues.
Peeing outside the box is often referred to as inappropriate urination, but it’s important to understand that from the cat’s perspective, what he’s doing is never inappropriate. There’s always a reason – and it’s not because your cat is trying to get back at you for something.
Always rule out medical problems first
Anytime a cat stops using the litter box, a trip to the veterinarian should always be your first step. Inappropriate urination can be an indicator of a serious health problem. Your veterinarian will perform a thorough physical exam and a urinalysis. Bloodwork and radiographs may also be necessary to diagnose the problem.

The difference between spraying and inappropriate urination
Cat guardians often confuse urinating and spraying. Urine spraying is a territorial behavior. Cats stand upright and deposit a small amount of urine on vertical surfaces. Cats who are urinating usually squat and deposit larger amounts on horizontal surfaces. Even though both male and female cats spray, the behavior is mostly seen in unneutered male cats, and occurs more often in multicat households, although even a single cat may spray.

Urinary tract issues and stress
Urinary tract disease is one of the most frustrating conditions to diagnose and treat in cats. It’s not always possible to identify the exact cause, since most of the affected cats have more than just one single problem. In 2011, a study conducted at the Ohio State University on 32 cats over a three year period found that stress has a significant impact on lower urinary tract health.

Destroy the evidence
Once a cat has peed outside the box, he’s drawn back to the area and considers it an appropriate urination site, which is why it’s important to eliminate all traces of odor from the trouble spot. Read Stain and Odor Removers That Get the Job Done for some of our favorite products.
Find the right litter box
The average cat uses the litter box three to five times a day. It would make sense that something that is used so frequently on a daily basis requires that we humans put a lot of thought into it. Unfortunately, cat guardians often select a litter box for all the wrong reasons – or at least for the wrong reasons from the cat’s perspective. Read The Optimal Litter Box for Your Cat to get a better understanding of what is important to your cat when it comes to the right litter box.
When all else fails
If you’ve tried everything and still can’t get a handle on the problem, you may want to consider working with a feline behaviorist.
