Another way to kill rabbits is reach in through the top of the pen and grab it like you would a cat. Grab its back legs then swing it and slam its head onto a stump or something. It knocks it out and sometimes kills it. Then lay it down on the stump and chop its head off. Then chop its legs off at the elbows. Gut it. Skinning it is easy. Make you a cool rabbit hat, slippers, etc.
