Good suggestions by GoldenMom. I don't have the breakdown anywhere but the back of my mind now

.
I buy whole chicken and cut it up for the dogs AND cats. I eat vey little meat but I do like chicken breast. So we all share.
The cats get: necks, wings, and the backs cut up the back to break the back/ribs (they are then easier for the cats to go for) I do this with turkey too. and rabbit when I can get it. I have never ground for them and have had them both since they were kittens.
They get proportionate amounts of organ meat (BABY fingernail sized pieces). And I feed all they will eat in one sitting. They are active indoor outdoor mousers. One is 3 1/2 years old and one is 9 months old. In decent weather they feed themselves rodents and rarely ask for a meal.
Since the wings tend to have so much bone I tend to feed just an "only meat meal" the day after every wing day. Hunks of pork, beef or lamb to get a good percentage "over time".
Especially for taurine I will feed only heart one day a week + with meals. Pork, lamb, beef, chicken, turkey, venison... anything I can get, but lots of heart. My cats are in great shape, and they LOVE their raw food. Though they would sell their souls for a few pieces of kibble - lol their version of kitty junk food.
Once a week I feed different types of canned fresh or frozen fish (more often if I have it). I especially look for fish with bone-in too. I also will offer a raw egg mixed with canned fish occasionally too - they think that is "ok" - not a fave. I have fish oli, but only give it about once a week.
I too, cut them up on one day (most of the time) and pre-bag enough for both cats to defrost every couple of days. Or a bag for dogs and cats all in one. I just cut different sized chunks.
I have been raw feeding for almost 8 years so I rarely give it much thought anymore, but at first I spent a lot of time researching & planning (I think that is why it is so easy now).
I don't feed bite sized pieces - think simple here

. When I have a hunk of meat I will cut strips up it, but leave all of it attached. I cut into it to make "fingers" or a "fringe" so they have something to grab and work off, instead of a solid square hunk - hopefully that made sense.
So nice when I took my cats in for checkups and the vet put her hands on them and said "Ah... nothing like the feel of a rawfed cat!" Who knew? They are solid, but not at all fat, and nice to have a vet who agrees with it.
Good luck!
