we use to have a newfoundland dwarf rabbit. he was great, small but had a really big attitude. he ran around the house when supervised and had a pen otherwise. he would put our dog and cats in there places along with us. he would growel when he didn't want to be bothered and would take a bite if that didn't work. thought he was a dog i guess. as for feeding he liked certain things and certain things didn't like him, just like any other animal. you need to figure out what is good for him and whats not. he was a 2lb ball of trouble but was one of the most enjoyable friends we ever had. when we lost him it was like losing a best friend.
