Some Days My Cat Just Wants to Pee on Everything! I hear this from clients.
Urinating inappropriately is the most common behavioral reason cats are euthanized or "let out" or relinquished to shelters is for inappropriate urination in the house. The most common reason they do this is a condition called Feline Idiopathic Cystitis (FIC) literally means an inflammation of the urinary bladder in cats of unknown origin. It is also called Feline Idiopathic Lower Urinary Tract Disease (FiLUTD) or Feline Urologic Syndrome (FUS). Recently, it has been called "Painful Bladder Syndrome" (PBS).
FIC has been estimated to affect up to one percent of the cat population, making it one of the most common conditions seen in cats.
Despite many years of research, the cause of FIC remains unknown. Factors that may play a role in the development of FIC include viruses, type of diet fed (especially dry food diets with high mineral content), stress, confinement to a strictly indoor environment, and genetic factors (longhaired cats, for example, seem to be more commonly affected).
Treatment often involves a change in diet from a dry food to a canned food and attempts to minimize stress in the animal's environment.
Regardless of the cause, one result is that the cat urinates outside of the box, leaving urine odors around the house. This can be intolerable to cat lovers. I know (from personal experience).
It is important to remove all traces of the urine odor to help prevent your cat from going back to that spot. One "accident" on the carpet, bed or sofa is bad enough. Repeat urinations are the worst (and it is even worse this time of year as it is getting humid). And once a cat goes in one area or location, it is common for them to go back to that area.
Over the years, I've looked high and low for a good product that will work on urine odors and after years I found one. I love it. It is called Zero Odor.
It works by neutralizing the stinky odor molecule. It doesn't cover the smell as many products do. It has really worked for me. So, if your cat has ever urinated outside of the box – try Zero Odor.
If your cat is experiencing any urinary problems – see your veterinarian to ensure your cat doesn't have a medical problem such as an infection or stones.
I hope this information helps you understand why cats pee outside the litter box.
