Product Information

Royal Canin® Urinary S/O is a veterinary exclusive dry food specially formulated for adult cats with urinary health concerns. By helping to increase the amount of urine your cat produces, this specialised diet helps dilute excess minerals that can cause crystals and stones. Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. With a reduced level of magnesium, this unique nutrition helps dissolve pure struvite stones and helps prevent calcium oxalate stones from forming. Mix with your cat’s complementary Royal Canin® Urinary S/O Wet Cat Food to give it a texture that pleases even the fussiest eater.

Frequently Asked Questions

Dry diets should be stored in their original bags and resealed between feeding. Most small bags include a re-sealable zipper. If the bag does not have this feature, it’s recommended to keep the product in the original bag and store in a dry, airtight plastic or steel container with a lid.

For dry diets, palatability of the kibble remains at its best for one month after the bag is opened, however will be fine for up to two months so long as the bag is stored properly, in a cool, dry, airtight container.

Introducing your pet onto a new diet should done gradually over 5 - 7 days to avoid the possibility of digestive upset. We suggest:

    Mix 25% of your new diet with 75% of your pet’s previous diet for 2 or 3 days

    Then mix the two diets 50% and 50% for 2 or 3 days

    Then mix 75% of the new diet with 25% of the previous diet for 2 or 3 days

    You can now try feeding with 100% of the new diet.
