If I understand it correctly at least some of the bone goes right in the grinder...remember in the wild cats eat the bones of their prey. After many years of having barn cats who were mousers the only thing I would ever find of a mouse was the tail, everything else was eaten.. They get their calcium from the bones. I know here I can get without a sale, 10lbs of chicken hindquarters for a little under $7 from the grocery store of course I would rather get whole chickens for $3 each from my egg and chicken lady because her chickens are HUGE fully dressed out they look like little turkeys..lol. She has Rhode Island Reds and Leghorns...those guys are big chickens. If I roast a whole one for us humans we eat on it for at least 3 days and then I end up boiling down the carcass to make soup or chicken and noodles casserole and still have scraps for the critters.
I know the last time I was out to her place to get eggs the roosters came up to about my thigh. And have some very pretty plummage which I am still thinking about talking to her about saving for me to make feather earrings and the feather hair extentions that are all the rage now. As she is a very furgal little only german lady and the more parts of the bird I take off her hands the deeper the discount on the eggs. ;-) That is actually how she and I hooked up, I had a rescue here that there was just no taming, she was feral as the day is long, so I advertised her at my vet's as a barn cat, and my egg lady took her in to keep the mice out of the chicken feed. So I get 36 eggs now from her for $2. And her large eggs make the store bought large look like humming bird eggs. :lol: And if I bring back the cartons she only charges $1.75 for 36.
Also once hunting season opens DH has lots of coworkers that like to hunt but only use the big pieces of meat so I'm sure I can cut them a deal for the scrap meat, and some of the ducks and pheasants. I could probably get rabbits too, just not trust wild rabbit as there as been problems with disease in them around here every now and then. But I think the cats would love a little game meat as a change of pace off the chicken as well.
Also you are only feeding 2....I'm feeding 14 plus a drooler in a town where the nearest petsmart or petco is 200 miles away so I don't even have access to the better quality canned food, except at one store where it is $2.56 for a 3oz can of Wellness...so not happening with 14. And if I want other than 3 flavors of 9-lives that Walmart carries (when they actually have it stocked) it is $2.09 for a 4 pack.
