How about not grinding up the meat or bone? I got my Sasha at 3 months and he's been eating Frankenprey since then. He's not that good at thigh bones just yet. He's now about 7 months, but he can eat a chicken wing, back, ribs, etc like nobody's business.
I just don't see why grind up the meat if you are going to have to add stuff to it later, but maybe that's just me *shrugz*
Now having said that since your cat has eaten ground all this time, you will have to start with small bones to work up the jaw strength, but it can be done and makes it so much healthier for their mouths and spirit. There is nothing like watching a cat channel his inner lion...lol. Feeding bone this way is also pretty much self-regulating as far as their bowel movements. You won't have to obsess over measuring supplements and what nots.
