Consider your catвs current or past medical conditions. Your catвs medical history may provide an explanation for why your cat has not been using the litter box. If you suspect that your cat is sick, take her to see a vet as soon as possible. Early treatment of an illness by help stop litter box problems as well as save your cat from pain and discomfort. Urinary tract infections and feline interstitial cystitis are common conditions that may cause your cat to urinate on the carpet.
Urinary tract infections may cause a cat to avoid the litter box, even after the infection has been treated. Your cat may still associate the litter box with pain and want to avoid it. Feline interstitial cystitis is another common cause of litter box aversion. Cats with feline interstitial cystitis may urinate in the litter box because they feel the need to urinate more often.
Kidney stones or a blockage of your catвs urinary tract may also result in a litter box aversion. Your cat may meow or howl while using the box and the fear of pain may continue even after treatment. Keep in mind that prompt treatment of these conditions is essential so that your cat does not develop a long lasting litter box aversion.
Be sure to thoroughly clean all areas where your cat has peed outside the box.
You want to be sure you ve eliminated the odor, not just for your own sake, but also so the smell doesn t draw your cat back to that same spot. Use a black light and your nose to identify all the problem areas. If you are dealing with fresh urine, first blot up as much as possible with paper or cloth towels.
Next (and for older spots), pick the best cleaning method based on what has been soiled. Hard surfaces can be thoroughly cleaned with your favorite household cleaning solution. Use your washing machine for bedding, towels, etc. Rugs and upholstery are best cleaned with an enzymatic or bacterial cleaner, but make sure to follow the manufacturer s instructions to maximize their effectiveness.
