We do what's sometimes called "frankenprey" (because all the components of an animal the cat needs to eat are made up of different animals such as chickens, beef, turkeys, etc, rather than whole prey (such as small mice, chicks) that would be too gross for me. No supplements, he gets what he needs from the meat.
Here is what my 11 pound cat eats, over, say, a week.
He gets two meals a day, to satiation. I know about how much food he eats now, in the beginning, I experimented. If he still seems hungry, he gets more If he doesn't finish it (he can't finish a chicken leg or theigh in one meal) it goes back in the fridge in tupperware after 30 minutes, and goes back out for his next meal. Extra meat more than a day or two's worth is kept in the freezer (flash frozen on a baking sheet, then put in cleaned yogurt quarts)
-Chicken legs or theighs, turkey legs or thighs, beef stew meat or beef scraps (and other non pork meat as availible/affordable). chicken gizzards also
-A piece of liver (chicken, beef, whatever else we have/find. duck is usually reserved for the two footers, cause it's so tasty.) about the size of a dime to a quarter every 3ish meals (not exact. Might be two, might be 4)
-When he didn't eat meat off the bone, he got eggshells about the same frequency (cleaned, dried, crushed by hand and stored in the freezer). Now he gets them less frequently, because he seems to eat a little bone as he eats the meat off the bone (meat on bone is about 2/3 of his meals lately) hopefully I'll transition to really eating some bone (like wingtips, necks, ribs) soon.
-He was getting chicken heart, oh every other day, but he wasn't doing well with that (throwing up shortly afterwards only on meals with hearts) so while I track down another source of meat, he's occasionally been getting little bites of goat heart (but the goat heart is for me! I pay way too much for my pastured goat hearts for him to get a lot) and relying on the fact that dark meat is richer in taurine. If this ends up a long term problem, not one fixed by finding another source of chicken hearts, then I will track down other sources of non chicken hearts that are cheaper or supplement taurine. this counted as part of his "meat"
-I'm still looking for sources of kidneys, sweetbreads, etc. I admit, I haven't been looking too hard, I figure he can do without for a little while, and I don't have the energy atm, work is particularly stressful and tiring this month
Basically, I roughly keep in mind 80% meat (including gizzards and hearts) 10% bone and 10% organ (not all liver.) I'd say he gets less liver and less organ than that right now. He seems just fine.
(also helpful is knowing that bone helps firm up poops, and organ loosens it. If the cat has diarreah, try feeding more bone/eggshells and less organ. if he's constipated/his poops are VERY firm, try feeding more organ and less bone/eggshells. (though I'm also very sensitive to the fact that in a small animal, something like that could be the only sign you get of a very sick animal, and if he has diarreah or seems slightly constipated (not extremely), I really would only give it one meal to see if it's the balence. I've found that adding a normall meal's worth of egg shells (a small pinch) to his next meal has firmed it up, and a normal amount of organ in his next meal loosens things up. I do pay attention to if he's otherwise looking good (play, energy, snuggles etc).)
check out the rawfeeding and rawcat yahoo groups, they are so helpful!
(in terms of the constipated cat, it is normal for raw fed cats to only poop every couple days, so he's not nessicarily constipated if he doesn't poop every day. It freaked me out at first.)
re: dragging food all over. Until my cat got to whole legs/thieghs of chicken, he was great about eating on a plate (except the first three meals, where I sat with him, and put the meat back on his plate every time he took it off. which was about 15 times in his first meal.) At first with the whole theighs, he dragged it out of the bathroom (where he eats), into the main room to eat. I would pick up his food, put it back on his plate and shut him in the bathroom til he finished (this is why he eats in the bathroom, the kitchen doesn't have a door), then clean up the carpet. Now, he does tend to drag the meat off the plate, and onto the bathrug next to it, and I pick it back up when I see it and don't worry too much. I know some people feed on towels (I think the plates are too slippery with such big peices), but I don't have extras.
) are much better. They exercise your animals jaws, and have a tooth cleaning effect, which helps their teeth. (animals who have eaten kibble for a long time sometimes have bad teeth and sometimes can and sometimes can't manage whole chunks of meat.) You will have to start with small peices and slowly increase them, as your animals learn to chew and increase their muscle strength.
