I feed my cat right from the start with Royal Canin. First Outdoor gave because they are outside in their enclosure summer, and it is assumed to be a lot of fun. And when they were in winter more are in the house I have just times Royal Canin Indoor, and it is of just as happy "eaten". Even my vet says that Royal is a very good cat food. The price on Amazon is unbeatable anyway and also supplies very quickly. I and my cats are completely satisfied.
