It's not actually fully hypnosis the bunny, but more likely to put the bunny in a trance. In a trance position, it's very useful to trim the toenails, give a medicine or calm the rabbit.
1. Pick it up with your right hand under the front legs and your left hand on the butt
2. Then stick the bunny in the crook of your elbow just like cradling a baby
3. In that position, use your right hand and start petting the bunny's face
4. Once the bunny looks relax, the head will start to fall backwards and then the bunny is in a trance position.
Don't get it? Watch this guy hypnotize his rabbit.
Practice makes perfect. If your bunny struggles for the first time, be patient and keep trying.
Good luck in hypnotizing your bunny!
