Feline Idiopathic Cystitis PDF Print E-mail

Feline idiopathic cystitis is a painful condition which afflicts both male and female cats.  Inflammation occurs in the bladder when the cells lining the bladder wall temporarily stop producing a protective glycoprotein that spares the cells from the caustic affects of urine.  The cause of this is unknown but it is believed that stress can sometimes bring it on in the susceptible cat.  The result is an inflamed bladder lining with resultant painful and frequent urinations---sometimes with blood in the urine.  Theses are identical signs to those seen with bacterial bladder infections.  But in the case of feline idiopathic cystitis, bacteria are not involved.

The problem is self-limiting and usually resolves on its own in 3-5 days but is very distressful to the affected cat and the cat’s owner until it does clear up.  Relapses are quite common.  A veterinarian can prescribe painkillers to help the cat deal with the discomfort.  Increasing water intake with canned food and good availability to fresh, cool water can also help.  In addition, veterinarians often prescribe special diets that reduce the recurrence rates and severity of this condition.  

This syndrome is diagnosed through clinical signs, a thorough physical examination, and a urinalysis.  In addition, abdominal radiographs and a urine culture may be required in some cases.

When male cats acquire this condition it can become more dangerous since it can lead to urinary blockage because the male cat’s urethra is narrower and longer than a female’s urethra.  When the cystitis occurs, crystals can develop which then form into concretions that block the urethra.  For this reason, when a male cat is having a difficult time urinating, it should be considered an emergency and the cat should be examined by a veterinarian right away.
