My friend keeps a rabbit hutch in her yard, and,.. true story; the rabbits were all female and they wanted a male so they trapped one but it would do nothing but eat and sleep. So the vet told them the rabbit was too old to mate. So the vet tells them that he knows someone who has young males that they could get. Now my friend says this male rabbit humps like a mad man.They are up to their necks in baby bunnies.
