Feline lower urinary tract disease causes painful urination difficulty and crystals that can lead to life-threatening obstruction, with diet modification and stress reduction being the most powerful welfare interventions.
FLUTD cats experience painful urination as their primary welfare impairment - straining in the litter box, crying during urination, and frequent unsuccessful attempts communicate the intensity of their discomfort. The stress trigger for FIC means that household environments play a direct welfare role. Multi-cat households where resource competition creates stress between cats generate chronic FIC flares. Environmental enrichment, multiple litter boxes, and reduced inter-cat tension treat the welfare-undermining cause rather than just the symptoms. Wet food feeding is the most consistently impactful dietary modification for long-term urinary welfare.
