Feline Idiopathic Lower Urinary Tract Disease

Idiopathic Feline Lower Urinary Tract Disease (IFLUTD) is a universal term for conditions represented by blood in the urine, urinating in inappropriate locations, difficult or painful urination, abnormal or frequent passage of urine.
IFLUTD is also called Feline Idiopathic Cystitis (FIC), Feline Urologic Syndrome (FUS), or Interstitial Cystitis. These diseases occur due to the bladder and/or urethra inflammation without any physical cause and are idiopathic.
