  • Fluffed up fur

    By on

    After a month of Royal Canin adult dry and wet food I notice her fur looks extra fluffy. Cat.fur tells a lot about a cat's health.

  • Best food for cats

    By on

    My 5 cats really like both the kibble and the canned food. Their coats are shinier and they seem more active. I wish you would make a case of different varieties so I could see which they like best.

  • My cats love it!

    By on

    I won a contest at my Vet office and I won a year supply of this food. My 5 cats love it! When I'd use different cat food they would be picky and not eat. They always eat this food!

  • Great for finicky eaters

    By on

    I have a cat who is a very finicky eater and he has been consistent with eating this product. He also has some difficulty eating due to a stroke but manages to pick up the pieces well due to the cross shape of the pieces. The best dry food by far!

  • Cats love it

    By on

    My 3 cats all love this food, which is saying something because 2 of them are very picky. I chose this food because it has SO index, which gives me peace of mind regarding urinary issues/blockages.

  • My cats love this food

    By on

    The food is expensive but it works for my cats. They do no get sick from it. It is cheaper to order on line than from the vet. I will like the automatic shipping to my home.
