I'm thinking of changing Tibby and Corkscrew's food, they are currently eating Science Diet. I'm looking for something that's higher quality. I'm thinking of getting Nutro Natural, but I'd like to get some other suggestions. I normally shop at PetSmart, so I would prefer that it is a food that is sold there. I would like to feed something like Chicken Soup or Canidae, but the only store in towns that sells it also sells puppies and kittens so I refuse to give them my buisness, so those two brands are out.
