One of my cats eats fresh rabbit as part of her diet. I buy a whole one and freeze what I won't use that day. I give her roughly a whole front leg 4 times per week and she never finishes off all the bone.

The first time I introduced it to her, I chopped it into 2 inch pieces (with bone) and just gave her 2 bits with some mince she likes. I've built it up very slowly from there and now she chomps on a whole leg.

I was advised to introduce bone very slowly as there's still a risk of them getting it stuck; I've seen her gag on the bone a few times which worries me.
