Cat Not Using Litter Box? Inappropriate Urination in Cats

Cats that urinate outside of the litter box might have a medical problem.

Inappropriate urination is the most common behavioral problem reported by cat owners. It is a leading cause of cats being abandoned outdoors, left at shelters, and euthanized. There is no doubt that it is extremely frustrating to have a cat that is urinating on your carpeting, bedding, or clothing. Most cases of inappropriate elimination can be resolved, but it may take some detective work and adjustments to your household to achieve it.

Why Do Cats Use Litter Boxes?

Many of us assume that cats use litter boxes instinctively. Actually, their impulse is to eliminate in soft soil or sand. The box is a convenience for humans, and it's really rather amazing that cats are so accommodating about it. Understanding this point will be a great help to both you and your cat. Elimination is a basic necessity, but in cat terms this function has an additional meaning. Cats sometimes use elimination as a communication tool to help establish their territory. So if your cat is not using the litter box, he may be trying to communicate something.

What is Inappropriate Urination in Cats?

It is important to differentiate between the two types of urinating outside of the litter box: spraying and inappropriate urination.

There is a difference between feeling spraying and urinating.

Spraying is performed by the cat standing and spraying a stream of urine on a vertical surface such as a wall, window, furniture, drapes, etc.
