This is a pic of one that Kato's in the middle of eating right now.
It's about 5" in length. The bone is from a cow and I think it's the femur.
I don't cook them. I also remove some of the marrow because my dog has a funky stomach.
Hope that helps!
PS...How about some new Kozmo pics?
Those bones really from cows? I asked my mother and she said cow bones shouldn't be that thin. Is it from pigs?
