RAW FEEDERS ONLY PLEASE-Should I give bones to a 16 year old recent raw convert?

My two spayed female cats ate kibble for the first 14 years of their lives, (one is now 15 and one turns 16 in July) and than I guess I grew a brain lol. They now do still have to eat a bit of urinary kibble to prevent UTIs but eat mostly raw organic grass fed red meat and organic free range poultry and have been for about 6 monthes when I switched my puppy. Before that they got a lot of By Nature Organics grain-free canned. They love it and it's improved their health so much just in the six months that it's unbelievable. I'd been giving them commercial Paw Naturaw raw poultry patties (originally bought for the puppy, who refused) and recently started giving them some of the ground beef I had for the puppy (she absolutely will not eat bones so I give organic eggshell powder instead) I had been tearing it into tiny pieces for them under the assumption that if the puppy wouldn't eat it in one piece, neither would they. I was tearing up the pieces for my younger cat Tigger when lo and behold Tabitha didn't want to wait and attacked her portion whole and tore it up all by herself. I ws so proud of her! . Anyways, this leads my to believe she'd have no problem with tearing meat off of bones and possibly even consuming the bones themselves. Tigger still needs hers torn into itty bitty chunks unfortunatly, but I would LOVE to be able to give at least Tabitha raw meaty bones for the dental benefits but don't know if I should-she didn't grow up eating bones at all and I'm afraid she won't properly chew (her teeth aren't bad but not in the best shape) and end up choking. Also, what are the softest. easiest bones to start with? I'm thinking maybe chicken necks? Or maybe even day old chicks if I can find them? I'm not averse to anything no matter how expensive or gross as long as I can get it organic. .Since my puppy won't touch bones I've never fed them. Thanks!
