However, bacterial cystitis accounts for only a small fraction of all feline cystitis cases—only 1-3% according to Alleice Summers, DVM. In her book, Common Diseases of Companion Animals, Alleice also outlines a study run at Ohio State. During this study 132 cats were examined specifically for symptoms of cystitis and 61% of them were found to have something called idiopathic cystitis –not a bacterial infection.

How do you confirm and treat bacterial cystitis?
A urine culture will help your veterinarian determine if your cat
