The nutritional formula in ROYAL CANIN® Urinary Care is carefully balanced to support the health of your cat's urinary tract. By controlling the mineral balance and preserving a low urine pH, which results in less concentrated urine, ROYAL CANIN® Urinary Care is a unique formula that keeps healthy urine concentration. With a low pH in the urine and a perfectly balanced mineral composition, along with a high protein content and optimal vitamin levels, ROYAL CANIN® Urinary Care is the perfect cat food. Urinary health is a vital component of a cat's overall wellness, so it's important to consult your veterinarian to evaluate your cat's urinary health and to help maintain it in compliance with their recommendations, which may include changing the diet you feed your cat.
