Urinary tract infections in cats under age 10 are often not infections at all, but rather painful collections of tiny stones or crystals that irritate the walls of the bladder, causing discomfort and pain. In male cats, they can be very dangerous and even fatal. While antibiotics won't get rid of stones or crystals, they can make the cat more comfortable by reducing inflammation and preventing secondary infections.

Diet plays an important part in preventing urinary tract infections (UTIs) and Feline Lower Urinary Tract Disease. Cats who are prone to UTIs do best on an all-wet food diet, which keeps them well hydrated, and creates dilute urine and an environment that is inhospitable to the formation of crystals and stones.
