I have a rabbit that is almost a year old. He has been neutered, and I have raised him since he was a baby. He has never been aggressive towards me before, but about a month ago he started becoming food aggressive with my fiance, then recently...me. He grunts, lunges, bites, and claws when I try to put food into his cage. He's not like that with his female companion, who is spayed. I don't know what to do! He bit me the other day and drew blood, and last night he clawed my hands. Somebody please help!
