After reading all the posts on upgrading cat food, I decided to change my cats' diet. I had been giving them friskies and whiskas (didn't know any better) and stopped by petsmart today to pick up some nutro. They had nutro kitten formula and nutro gourmet choice kitten formula. I ended up going with the gourmet choice and my kittens seem to like it. Does anyone know the difference between nutro and nutro gourmet choice?
