How I will stop my rabbit by biting everyone?

This is a common thing many rabbit owners complain about. If your rabbit is unfixed, fix him/her. He might need more toys. He also needs to bond with you. Spend time bonding with him by laying down, and setting treats on yourself. He won't bite you like a rabid dog, he only bites when he feels pressured and unsafe. You need to bond with him. Try giving him treats more often, and talking to him in a happy tone. Let him out more. Show him love. Handle him correctly, and reduce the amounts of times you reach into his cage. When you open his cage, let him come to you, not the other way around. It may take weeks, but truthfully, a mean rabbit is just a frightened, confused rabbit.
