I have a 5 month old kitten, Elliott. I also have a dog, Riley. Even though Elliott has dry food at all times, he always wants to get into Riley's dry dog food. The both eat Purina food. Is the taste similar for the dog food and the cat food. The pieces are similar in size. Will it bother Elliott eating dog food? He doesn't eat alot, just a few pieces here and there before I put Riley's dish away from him.
