Feline cystitis: a case presenting with LUTS in a young female cat.

Feline lower urinary tract disease (FLUTD) is a term often given to cats exhibiting certain clinical signs, including straining to urinate, haematuria, pollakiuria, and periuria. Although periuria (urinating inappropriately around the house) is the clinical sign that most often initiates the visit to a veterinarian, the clinician must differentiate cats with lower urinary tract signs (LUTS) indicative of underlying disease from those with behavioural issues. Despite extensive diagnostics, at least 70% of cats presenting with LUTS will have no identifiable cause (e.g. urinary stones, urinary tract infection), and are thus categorised as having feline idiopathic cystitis.
