I am such a fan of Innova - Penny Lanes coat has glistened since I have had her on it. I have to qualify it however since she was on cheap food when I adopted her from the shelter. Leo - who has a very sensitive stomach seems to have less trouble digesting this food than the Science Diet I had him on before. I also think that it is the same price as some as the others as I don't have to feed him as much to get the same nutrients.
