No problem. We had our nutrition portion in school about 3 months ago, and learned about many different kinds of pet foods. I'm not in any way saying science diet is the best food, but I do believe they make great foods for animals that help maintain their health issues!
I agree with corn as an ingredient, many animals are allergic to it, and it's just a filler that really doesn't do anything. I'll mention California Natural to my instructor, thanks!
