Most of the premium brands (Blue Buffalo, Canidae, Orijen, Royal Canin) should be fine. Stay away from store or discount brands as these typically contain low quality ingredients and more fillers. Choose a canned food that comes from the can looking like a hockey puck. It should have a named protein source of animal origin. If you must feed dry, choose a grain free diet. Stay away from foods that are minced, diced or have sauces/gravies. these are usually higher in carb content which your cat does not need.
