Feline idiopathic cystitis is a common disease of unknown aetiology. Despite numerous studies, our understanding of this disease remains poor and knowledge of effective therapeutic intervention is also rudimentary. Feline lower urinary tract disease (FLUTD) is a common syndrome seen in veterinary practice, and probably accounts for around three to five per cent of feline cases seen in general practice. The most common identifiable causes of FLUTD include bacterial cystitis, urolithiasis, urethral strictures, urethral plugs, trauma and neoplasia. When investigations fail to identify a specific underlying cause, feline idiopathic cystitis (FIC) is diagnosed. In most studies, FIC is the most common diagnosis made, and generally comprises 55 to 65 per cent of cases. No specific breed predisposition for FIC has been reported and the disease has been reported in a wide age range, although it is most common in young to middle-aged adult cats; a typical mean age of around five to six years old has been reported. Some studies have found a higher proportion of male cats affected, and some studies also suggest FIC may be a common underlying cause of urethral obstruction in male cats. Some studies also suggest a higher risk of FIC in cats fed dry food, but further research is needed to determine whether there is a causal association. Obesity has been found to be a risk factor for FIC …
