Feline lower urinary tract disease encompasses a range of conditions causing pain, difficult urination, and in male cats potentially fatal urethral obstruction, making urinary health a central cat welfare concern.
FLUTD causes significant pain - the dysuria (painful urination) and lower abdominal discomfort cause cats to cry while straining, vocalize when touched in the abdominal region, and avoid using the litter box. Feline idiopathic cystitis, the most common form in young cats, is exquisitely stress-sensitive: any change in the household environment can trigger an episode of intense bladder pain. The urethral obstruction emergency creates acute agonizing pain from bladder distension before rapidly progressing to toxic death without emergency treatment. Many cases of FLUTD recur throughout a cat's life, making it a chronic condition requiring ongoing management. The stress-FLUTD connection means that addressing cats' environmental and psychological needs is genuinely a medical welfare intervention.
