Interstitial cystitis in cats

Despite much research on FUS, there still is no consensus regarding its cause, or even its definition. We recently have demonstrated that some cases of FUS are similar to interstitial cystitis in human beings. Exclusion of anatomic defects, behavior abnormalities, neoplasia, urolithiasis, urethral obstruction, and urinary tract infection leads one to the diagnosis of interstitial cystitis in cats. This diagnosis suggests the need for new approaches to treatment, including pain management and environmental modification.
