Lower urinary tract disease in cats — including cystitis, urolithiasis, and urethral obstruction — causes significant pain and can be life-threatening, yet is frequently preventable through diet, hydration, and stress management.
Urinary disease in cats spans from acute pain during urination to life-threatening obstruction. Cats with cystitis strain repeatedly to urinate, often producing only drops while in evident pain. The stress-linked nature of feline idiopathic cystitis means that the disease is a welfare indicator for the psychological environment — cats experiencing chronic stress are at elevated risk. Urethral obstruction causes metabolic crisis within hours if untreated, and the pain of the blocked bladder is extreme. Prevention through dietary hydration, stress reduction, litter box management, and stable multi-cat environments can dramatically reduce disease incidence. The welfare implications extend beyond the cat to the human-cat relationship — recurrent urinary problems are a common cause of relinquishment.
