Feline idiopathic cystitis is the most common cause of lower urinary tract disease in young cats and is strongly linked to stress, with significant welfare implications.
FIC causes significant pain and distress during episodes, with cats straining repeatedly and showing signs of discomfort. The condition has a major impact on the human-animal bond when cats urinate inappropriately. Recurrent episodes cause chronic welfare problems. Urethral obstruction is an extremely painful emergency that can be fatal if untreated within hours.
