Several reasons why your cat is peeing outside the litter box

Why do cats pee outside their litter box?

Here are several causes of litter box problem and possible solutions you can adopt:

Stress and Anxiety

When your cat is stressed due to a change in environment, whether minor or major change, it can affect their behavior. For example, moving their litter box to another spot or allowing loud noises near their box can make them ditch the box and pee wherever they find peaceful.

A dirty litter box

Will you use a dirty toilet that smells so bad? Definitely No. Well, the same applies to your four-legged companions. If you do not clean their litter box regularly, your cat tends to consider peeing somewhere else.

Litter type

Not all types of litter work for every cat. Basically, kittens learn to use a particular type of litter from their mothers when they are barely three weeks old. So, bringing a different type of litter when your cat is already an adult cat could cause a lot of problems, and encourage them to pee outside the box.

The placement of the litter box

As we’ve mentioned earlier, when the litter box becomes hard to access, your cat tends to go elsewhere to do their business. Placing a litter box in a basement for an older cat to use many not work if the cat has joint issues or problems with their eyesight.

Multiple pets in your home

When you have multiple pets in your home, your cat tends to pee outside of their litter box, especially if there is a bully amongst them who stops the cat from getting into the box.

Medical Issues

When your cat constantly pees outside of their litter box, the first thing you should do is to call your vet. This way, most possible medical conditions can be checked and ruled out through simple blood and urine tests.

Kidney disease

This disease is common among aging cats and the most common signs include decreased appetite, increased thirst and urination, weight loss, and vomiting.


This condition is common in cats as they age. It is caused when the thyroid gland, which produces thyroid hormone that controls metabolism, becomes hyperactive. Your cat tends to vomit chronically, lose muscle mass and weight, vocalize more, and drink more water, which causes frequent urination.

Urinary tract infection (UTI)

If a cat suffers UTI, the bacteria in their urine can affect their bladder and kidney, triggering inflammation. Your cat tends to strain to urinate in small amounts, and sometimes the urine gets stained with blood.

Degenerative joint disease (arthritis)

When a cat suffers pain in their joints, they tend to avoid peeing in their litter box, especially when they would have to climb or jump into it.


Cats would love to pee in their litter box if all things stay the same, but when the factors state above starts to set in, your cat tends to go elsewhere to pee. If you notice this behavior in your cat, do not punish them. Instead, try to trace the cause of the problem. You can talk to your vet to know if there’s an underlying medical condition or psychological disorder.
