FIC/FLUTD/FUS(Urinary Tract Irritation in Cats)

Animals Affected



FIC, FLUTD, and FUS are synonyms for a painful syndrome in cats. FIC is currently the most commonly used name. Its symptoms, listed below, mimic those of bladder infections. FIC is characterized by inflammation of the bladder and urinary tract which can be chronic or recurrent. The urine of these cats often is very strong, and may have an abnormal pH. As well, the syndrome has been correlated with crystals in the urine.

Feline Urinary Obstruction

Animals Affected

Male cats


Feline urinary obstruction is a life-threatening medical emergency.  It occurs when a plug of mucus or a small stone lodges in the urethra and obstructs it.  Strong spasms of the urethra may contribute to the syndrome.  Because the urethra is the structure used to drain urine from the bladder, this situation makes urination very difficult or impossible.
