5 Questions about Feline Idiopathic Cystitis - FIC

In my last post, I talked about urinary infections in cats. But, if in case the veterinarians did not find any underlying cause for the urinary infection then we talk about Feline Idiopathic Cystitis or FIC.

What it is?

It is the inflammation of the bladder without any cause identified. According to VCA Animal Hospitals: "Feline idiopathic cystitis (FIC) is the exclusionary diagnosis made once all of the common or known causes of the clinical signs have been eliminated."

What are the possible causes?

  • In the clinic, we had many cats that after the veterinarian ruled out all the tests and no origin is found, an FIC diagnosis is declared and stress seems to be the main factor. Cats are very prone to be easily stressed by anything, change of food, change of environment, change of routine a new member of the family, or new cats.

What are the symptoms?

  • Difficulty of urinating or painful urination (Dysuria).

  • Increased frequency of urination (pollakiuria)

  • Blood in urine - hematuria

  • Urinating outside the litter box

  • Overgrooming

  • Blockage of the urethra (Stranguria), which is considered an emergency.

What is the treatment?

In this case, the most important changes would be the nutrition and the environment. In regards to the food, it should be for therapeutic urinary care, I would suggest :

  • Prescription Hills C/D Feline stress.

  • Feline Urinary SO of Royal Canin

  • UR Urinary Feline Formula

  • Increase the intake of water

For the environment:

  • If you have a multi-cat household, please be conscious that each cat needs her food station ) food, and water.

  • Dishes need to be clean, cats are very picky.
