Cat Litter Box Problems (cont.)
Medical Problems That Can Cause Inappropriate Elimination
Urinary Tract Infection (UTI)
If your cat frequently enters her litter box and seems to produce only small amounts of urine, she may have a urinary tract infection. See a veterinarian to rule out this possible medical problem.
Feline interstitial Cystitis
Feline interstitial cystitis is a neurological disease that affects a cat's bladder (“cystitis” means inflamed bladder). Cats with cystitis will attempt to urinate frequently and may look as if they are straining, but with little success. They may lick themselves where they urinate, and they may have blood in their urine. Feline interstitial cystitis can cause a cat to eliminate outside of her box, but this is only because of the increased urgency to urinate and because there is pain involved in urination. Feline interstitial cystitis is very serious and can be life-threatening to the cat. It must be treated immediately by a veterinarian.
Kidney Stones or Blockage
If your cat has kidney stones or a blockage, she may frequently enter her litter box. She may also experience pain and meow or cry when she tries to eliminate. Her abdomen may be tender to the touch.
Other Behavior Problems to Rule Out
Urine marking is a problem that most pet owners consider a litter box problem since it involves elimination outside the box, but the cause and treatment are entirely different from other litter-box problems and therefore it is considered a rule out. A cat who urine marks will regularly eliminate in her litter box, but will also deposit urine in other locations, usually on vertical surfaces. When marking, she'll usually back up to a vertical object like a chair side, wall or speaker, stand with her body erect and her tail extended straight up in the air, and spray urine onto the surface. Often her tail will twitch while she's spraying. The amount of urine a cat sprays when she's urine marking is usually less than the amount she would void during regular elimination in her box.
