I figured this would be a good place to share some of my experiences in putting our kitten on full raw. He wasn't taking very well to bone, then someone told me to give him chicken ribs.
Chicken ribs?! Never heard of such a thing O.O
Yup, that's right. Chicken Ribs. They're very small and 1 or 2 ribs should get your kitty into accepting bones. Get a whole chicken and hack it apart yourself. Separate the sections of the chicken; quarters, wings, breast and back. Once you're left with the back, locate the spine. You'll see the ribs attached to it. The spine is easy to cut with a sharp knife. You can cut the ribs off the spine or cut the spine by sections of 2 ribs and then split the spine in half.
Your resulting pieces will be meaty and have small bones hidden inside them. I recommend offering when your kitty is most hungry. For Oliver, it was the morning time. He took to it right away and after a few of these pieces, he was interested in crunching down on other bones. YIPPE!
Good Luck with your kitties!
