We just introduced the kitten chow to general access this past weekend and up until then it stayed in the cage in the kitchen floor and the big guys wouldn't go into the cage (icky kitten cooties or something). Anyway, so far the kittens still love the Kitten Chow but will eat anything including Disney's food if hungry and the big guys still eat their Purina One with Ripley having a Kitten Chow chaser. I hope it doesn't change (knock on wood).
