FLUTD (Feline Lower Urinary Tract Disorder) is a syndrome seen worldwide in cats. Symptoms include; frequent urination, straining and pain, urinating in inappropriate places, blood, crystals or mucous in the urine, and urethral blockage (the most serious complication). Blockage occurs when crystals and mucous obstruct the urethra and is more common in male cats. Attempts to urinate are unsuccessful and the condition is very painful. Unless the obstruction is relieved quickly, kidney failure or even bladder rupture could result! If your cat is painful or collapsed, regard it as an emergency
