from rawfed cats: "As far as the amount of raw food to feed you cat, this will vary, depending on things like your cat's age, weight, activity level, metabolism and overall appetite. A basic guideline to use when determining how much food to feed your cat each day, is between 2 and 4% of your cat’s ideal adult weight. But remember, this is only a guide. Some cats will eat more than this, and some might need less. Ultimately you’ll need to let your cat be your guide when deciding how much to feed him. If he’s looking a bit pudgy, give him less food. If he’s getting a bit lean, increase the amount you feed him. Because every cat is different, there’s no exact standard formula."
