I am using Royal Canin. I have used the kitten, indoor adult for Jasmine and also obesity management for some time to help Peppito loose extra-weight. Now he is eating the light food for sterilised cats. It's often said Royal Canin is the best food, I don't know if it's true, but at least it's among the best ones. What I can say is that the cats love it and I never had any problems with it. We don't have Felidae here.
