These are my top choices of quality canned food for maintenance in cats (for adult cats). Any of them would form a fine basis for your cat's diet, supplemented small snacks of dry food, as needed. The order is based mostly by my own cats' reaction to these foods, and as we know, cats will sometimes turn up their noses today at yesterday's favorite. The bottom line is that the best food is wasted, if your cat won't eat it, so don't be too focused on the numbers.

Its top named ingredients are Chicken, Chicken Broth, Chicken Liver, Duck, Salmon, Carrots, Brown Rice Flour, and Fish Meal. It has a pleasant aroma, a nice paté consistency, and my test cats dive into it every time it is served.
Guaranteed analysis: Crude Protein 9% min, Crude Fat 5% min, Crude Fiber 1% max, Moisture 78% max, Taurine 0.05% min, Ash 1.9% max, Magnesium 0.025% max.
Natural Balance maintains its own testing center for seven known toxins including melamine, for its Buy with Confidence program - a huge plus, in my opinion.

Some cats love it and will dive right in, while others turn their noses up at it every time. It's on the high end of the price range, so I'd suggest buying a can or two, before investing in a whole case. Top ingredients: Chicken, Chicken Liver, Turkey, Chicken Broth, Sweet Potatoes, Carrots, Natural Chicken Flavor, Guar Gum, Carrageenan, Flaxseed, Squash, Cranberries, Blueberries. Guaranteed analysis (converted): Protein 45.45%, fat 22.27%, fiber 4.55%

First named ingredients: Organic Chicken, Sufficient Water for Processing, Ocean Whitefish, Brown Rice, Flaxseed, Oat Bran, Guar Gum, Dried Kelp. Although pricer than most other premium foods, Newman's Own is well worth rotating in your cat's diet. Several other formulas are available.
My cats' reaction to Evolve is also an enigma. The food smells absolutely wonderful, and is a nice, juicy paté. They loved it when I first introduced it to them, but recently have been spurning it - a shame, because its ingredients are excellent, and the price is very reasonable. Top named ingredients: Chicken, Chicken Broth, Chicken Liver, Turkey, Ocean Fish, Brown Rice, Carrots, Cranberries, Cottage Cheese, and Peas. Guaranteed analysis: Crude protein 45.5%, crude fat 27.27%, fiber 6.82% I alternate this formula with
Evolve Seafood Formula for variety.
Innova EVO, made by Natura Pet Products, has to score high on any list of cat foods. The canned variety is no exception. Ingredients: Turkey, Chicken, Turkey Broth, Chicken Broth, Chicken Meal, Herring, Carrots, Whole Eggs, Salmon Meal, Natural Flavors, Guar Gum, Seaweed Extract, Apples, Tomato Flakes, Cottage Cheese, Herring Oil, Potassium Chloride, Apple Fiber, Inulin, Vitamin C, Sea Salt, Choline Chloride, Sunflower Oil, Beta Carotene, Vitamins/Minerals
Merrick Cat Food is considered to be "gourmet" food, and can be obtained in several different flavor combinations. As an example, the Merrick Southern Delight flavor contains Chicken, Chicken Broth, Catfish, Crawfish, Brown Rice, Fresh Carrots, Fresh Zucchini, Fresh Granny Smith Apples, Olive Oil, and other wholesome ingredients. The link offers a variety of eight different flavors in 3.2 oz cans; good for a quick trial.
This food, which contains
only Chicken, Chicken Liver, Chicken Heart, and Water Sufficient for Processing should not be used as an every-day diet for cats.(Even Dr. Wysong recommends alternating foods for a balanced diet.) However, for cats with high-protein needs, or cats with allergy problems, it is an excellent limited-ingredient diet for stabilizing a cat's digestive tract.
