Feline urologic syndrome (FUS) can be defined as dysuria and hematuria in cats of both sexes. The disease can be manifested by the following syndromes: 1) cystitis, 2) urethritis, 3) urethral plugs composed of mucoprotein, 4) mineral calculi, 5) urethral obstruction. FUS is estimated to affect approximately 1% of the cat population of the united states, accounting for up to 10% of the total number of male cats seen in veterinary practice.
