Excuse me? Do you not understand "Bobbitted?" Eh, probably before your time. OK, I will just say it - Thumbalina bit Sampson's penis OFF. Just like that, a gorgeous AFL buck became useless as a breeding animal (not fine as far as his owner was concerned, at any rate). One of my first Mini Rex bucks could not be left with a doe for more than a couple of minutes. The doe might be as cooperative as you please, but within a minute after breeding her, he'd be in her face, biting hard enough to draw blood. He was sweet as he could be with people, but I felt sorry for the does I bred to him. Opposite-sex rabbit pairs can be brutal to each other too; the big difference is that wild rabbits have acres and acres of space in which to run away from a rabbit when they don't get along, and we seldom have that kind of space in which to confine domestic rabbits. Trust me, I've seen some pretty nasty things in the 30+ years I've been breeding rabbits, but I usually prefer not to get too graphic about it.
