Feline lower urinary tract disease is one of the most common and painful conditions in companion cats, with stress being a primary trigger — making it both a physical welfare problem and an indicator of underlying psychological stress.
FLUTD causes acute pain during urination, urgency and frustration when unable to urinate, and in blocked males, rapidly progressing systemic illness that is fatal without treatment within 24-48 hours. The stress connection means that FLUTD episodes serve as a welfare indicator for the cat's psychological state — a cat experiencing repeated episodes is signaling that its environment is causing chronic stress. The most effective management combines pain treatment during episodes with environmental modification to reduce the chronic stress that triggers them, treating both the physical symptom and its psychological root cause simultaneously.
