FLUTD encompasses a spectrum of bladder and urethral conditions that cause significant suffering in cats, requiring dietary, environmental, and sometimes medical management.
FLUTD causes significant acute suffering — straining to urinate, producing drops of blood, crying in the litter box, and frantic grooming of the urinary area are all signs of considerable pain and distress. The stress-linked aetiology of idiopathic cystitis means that environmental welfare improvements directly reduce disease recurrence. Owners who address inter-cat conflict, litter box inadequacy, and predictability of routine in their households demonstrably reduce their cats' FLUTD recurrence rates — a direct welfare benefit from attention to the social and physical environment.
