I work at a pet store and the girl that orders all the supplies and food said that either Royal Canin or Nutro (can't remember which) is coming out with a food just for Siamese. The reason is because Siamese have longer jawlines and tend not to chew their food (I know mine doesn't sometimes!)...so this new food is a different shape and it kind of forces them to chew it. Has anyone heard of it? I think they are also coming out with something specifically for Maine Coons.
