The way he eats reminds me of every feral cat I've ever dealth with; it's as though it's their last meal so they take as big a bite as possible. For exercise try the Cat Dancer. It's a toy on the end of a curved wire. When you wiggle it, it jumps all around crazily and my fur posse goes nuts over it. I have to buy a new one, though, cuz Yodie Yodie is fast and she catches it and tears it off the wire. It gives them a lot of exercise.
