Thanks for the advice! So far, my cats are not too happy with the Solid Gold I put in their bowls. usually when I come home in the evening, their bowls are almost empty. Today, it looked as if they barely touched it!
I think that it a good idea to mix several foods up from the start, that way they are not so picky. My two have gotten very picky.

Cat Dad, I think you are right, maybe Sammy's fur is just different. I just never had a cat with that type of fur. He is fun to pet! I will however call the vet, just to make sure.
