Royal Canin Veterinary Diet Urinary SO Dry Food was developed to nutritionally support urinary tract and bladder health in adult cats. It dilutes excess minerals that can cause crystals and stones by increasing the amount of urine your cat produces. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. This specialized nutrition, with a reduced level of magnesium, can help maintain your cat's urinary tract health.
