I have a beautiful little rabbit who is nearly full grown (not sure how old she is) She is extremely friendly and when we go outside to pick her up she runs to the side of the cage and puts her paws on the side waiting until we pick her up. She grooms me while I am holding her and is an overall very friendly and inquisitive rabbit. While she is grooming me she often nips me however, is this affectionate or is she unhappy about something... I am not sure whether to tell her off or what?
