    Cat's urinary tract health support

    Our cat Cojo suffers from urinary tract issues and had some severe macrohaematuria and at one stage was close to kidney failure in the past, requiring iv fluids and lots of visits to the vet. Since he is on Royal Canin Veterinary Urinary dry Cat Food regularly there have been no issues!

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.
