My cat's favorites are Earthborn, Fussie Cat, BFF, and Tiki Cat. I would suggest going to the local pet food store and getting a wide variety of brands/flavors and see what your cat likes.
Some other good brands are EVO, Fromm, Halo, Lotus, Natural Balance, Nature's Logic, Go!/Now!, PureVita, Weruva, Before Grain, Blue Buffalo, California Natural, Evangers, Felidae, Holistic Select, Innova, Merrick, Nature's Variety, Solid Gold, and Wellness.
