I can’t answer all your questions, but I’ll try to answer some. First, there is no guarantee that your cat will eat raw. They can be kind of peculiar about switching types of food, so the first thing to try is to switch the cat to canned food. Pick up dry food and allow the cat to get hungry, not starving, just hungry, and then offer canned food. If kitty eats it, great!! If not, after an hour, offer the dry food for 20 minutes, then pick it up. Next meal time, offer canned food first again. You may have to offer quite a number of times before she will eat it, or you may be one of the lucky ones. Once you have your cat on all canned food, start the process over again switching to raw.
There are many people that do not give any supplements, but they are the ones that need to be really careful to feed whole prey raw. Your dog might not eat kale, but if they eat an herbivore, they will be getting predigested greens that the food animal ate. You can predigest your own choice of veggies but blanching and pureeing.
You can also feed turkey and fish, so beef, pork, chicken, turkey, and fish are plenty of different proteins, and maybe a few times a year you can find lamb.
I use premixes +-3 days a week and no premix the rest of the time. I want to be sure to cover my bases.
Soup bones are not RMBs. RMBs are bones that are soft and can be completely eaten at meal time. Ribs from lamb, pork, or calves are good RMBs. So are neck bones from those same animals. All parts of chicken and turkey have good bones in them too. You should be able to get heart and liver and maybe kidney for organs. Maybe you can occasionally get some whole prey, even whole prey grinds, from Hare Today or My Pet Carnivore, to make up for not feeding other organs.
You can feed grinds to your cat, if you make sure they have heart in them, or add a taurine supplement. It her meats are frozen, you need to make sure the water that separates out as it defrosts is mixed back in, because that is where a lot of taurine is lost. I get whole carcass grinds from Hare Today for my cats, both rabbit and quail.
