What a cute picture. Jack is the same, he will eat anything and everything, he is just so greedy. I think where they were starving before they were taken into the shelter is the reason, he now eats as if he has to cause he's not going to get anymore. I wonder if it's a psycological problem with cats that have had periods of starvation?
Though I guess some cats are just plain greedy if they haven't had a problem before! hehe
