|I don't know what the most nutritous cat food is, but Hunter on occasion will eat Orijen. He is on about 95% wet food diet. However there are occasions when I'm not home, so I'll give him a scoop of his dry to tide him over. He gets Orijen, the regular formula. Its grain-free. Here are the ingredients so you can judge for yourself:
Fresh boneless chicken*, chicken meal, fresh boneless salmon*, turkey meal, fresh chicken liver*, herring meal, russet potato, chicken fat (preserved with mixed tocopherols), sweet potato, peas, fresh boneless walleye*, fresh whole eggs*, fresh boneless turkey*, fresh boneless lake whitefish*, sun-cured alfalfa, pea fiber, fresh boneless herring*, organic kelp, pumpkin, chicory root, carrots, spinach, turnip greens, apples, cranberries, blueberries, licorice root, angelica root, fenugreek, marigold flowers, sweet fennel, peppermint leaf, chamomile, dandelion, summer savory, rosemary, vitamin A, vitamin D3, vitamin E, niacin, thiamine mononitrate, riboflavin, d-calcium pantothenate, pyridoxine, folic acid, biotin, vitamin B12, zinc proteinate, iron proteinate, manganese proteinate, copper proteinate, selenium yeast, Lactobacillus acidophilus, Enterococcus faecium.
