ROYAL CANIN® Urinary S/O food is specifically formulated with the needs of your adult cat in mind. Suitable for cats with urinary health concerns, the food helps to dissolve all types of struvite stones in your cat’s bladder. It also helps to dilute your cat’s urine to lessen the likelihood of crystal formation.


Because one of the natural components of struvite crystals is magnesium, ROYAL CANIN® Urinary S/O is exclusively formulated with a reduced level of magnesium to further support your cat’s overall urinary health.


As part of the ROYAL CANIN® Veterinary Range, it is important that this product is only given to your pet when recommended by a veterinary professional. To cater to each cat’s individual preferences, ROYAL CANIN® ROYAL CANIN® Urinary S/O is also available as wet food in either a delicious gravy or a soft and tasty loaf. If you’re considering mixed feeding, simply follow our feeding guidelines to ensure your cat gets an accurate amount of both wet and dry food for optimal benefit.

  • Struvite Dissolution - helps dissolve all types of struvite stones
  • Urine Dilution - urine dilution means urine is less liable to form struvite and calcium oxalate stones
  • Low RSS - the feed helps lower the concentration of ions contributing to crystal formation
  • Low in Magnesium - a natural component of struvite crystals

See instructions on product packaging. Adjust the amount according to the animal's individual nutritional needs. Factors including breed, age and activity level should be taken into account. The daily amount can be divided into 2 or more meals. Fresh water should be available at all times.
