Feline Idiopathic Cystitis

 
Feline idiopathic cystitis (FIC) is a frequent medical cause of house-soiling. Cats suffering
from FIC have increased frequency of urination, difficulty and pain when urinating, and
can have blood in their urine. This inflammatory condition can increase and decrease in
severity over time and is aggravated by stress, changes in diet, and other issues.
