Feline idiopathic cystitis, the most common form of FLUTD, is strongly linked to stress and requires environmental management alongside medical treatment for optimal welfare outcomes.
Feline idiopathic cystitis causes significant acute suffering through the same mechanisms as cystitis in humans - burning pain during urination, urgency, and the distress of involuntary voiding outside the litter box. Cats experiencing urethral obstruction face life-threatening uremia within 24-48 hours and extreme distress. The stress-driven nature of FIC means that management requires addressing the cat's psychological environment, not just the physical symptoms. Cats in chronically stressful environments - inadequate resources, conflict with other pets, changes in routine - cycle through repeated episodes. Environmental enrichment and stress reduction through predictable routines, adequate resources, and conflict management provide genuine welfare improvement by addressing the root cause.
