Does this new rabbit bite when near its cage?Some breeders, like myself, use the method of a stick and soap.Whenever the rabbits try to 'attack' me Igo get my stick ofwood and put a little dish soap on the end. I letit attackthe stick rather then my hand. So when the rabbit bites the stick itgets a nasty taste of soap. They quickly learn that when they bite itdoesn't taste good therefore majority stop biting.
Maybe you could try something along this line even if its not in thecage. Also rabbits don't like it when ya blow on their nose. Its a goodform of punishment that I use as well.
