A healthy bladder starts with the right balance of vital nutrients. Excess minerals can encourage the formation of crystals in the urine, which may lead to the creation of bladder stones. They can cause discomfort and lead to more serious problems that require the care of a veterinarian. Hill's nutritionists and veterinarians developed Prescription Diet c/d Multicare, clinical nutrition specially formulated to support your cat's urinary health. In fact, c/d Multicare is clinically tested nutrition to lower the recurrence of most common urinary signs by 89%. This irresistible food makes it easier for you to bond with your pet with gently cooked, bite-sized chunks of real tuna and natural ingredients with added vitamins and minerals.
