My (at the time) 1 year old rabbit hit his head pretty hard on the edge of his little house, he was and still is completely fine and living a happy and healthy life. I zoomed in on the rabbit in the beginning as I did not want to show some things. I cut some parts as they were boring, he wasn't doing anything, I just showed that he got up and then went for a second hit to the head. Sadly, the clip has bad quality, I can't do anything about it.
