Feline lower urinary tract disease (FLUTD) is common in indoor cats and is closely linked to stress, inactivity and inappropriate diet, with some cases constituting veterinary emergencies.
Cats with urinary obstruction experience severe pain from bladder distension, nausea and metabolic crisis. Even non-obstructive cases involve dysuria (painful urination) and repeated straining. The condition is strongly associated with environmental stress, meaning prevention requires addressing the root cause of cat welfare rather than simply treating symptoms.
