We have a rabbit male not neutered, he is about six months old. He only bites me... sometimes when I walk he will lunge at my feet. Most of the time he is a good rabbit and will follow me. Bit there are times when I will walk and he lunge at my feet... or he will spray me and start nipping at my heels. Anyone know why? I do not know his life before us. My husband friend found him near a tow yard.
