We adopted a new cat from the shelter. He will only eat dry cat food and only 1 or 2 brands. He likes SD naturals best chicken & rice which they just stopped making and he will eat some blue buffalo dry. He will only lick the gravy from caned food he will eat none of the morsels. He will not eat caned tuna, or peel and eat shrimp or chicken or any table food. He just paws the floor near where we put the bowl. We have bought almost every kind of cat food Petco sells only to have to give it to the shelter when he won't eat it.
