The store sounds like a winner to me. I hope that he'll like something and will eat more on his own. Good luck.

I feed all of my cats Innova Evo dry and wet and some of them don't really care for the wet as much either. With Storm I mix in some other grain free wet food and he loves it. Sunny won't eat the dry food by itself so I have to mix in the wet with it. They sure can be difficult at times.
