Oh forgot to tell mine did do a short hiss at me but quickly stopped. I am now nervous about him biting me he is still new and still settling in but I had to move over a bit to adjust thermometer probe ill tell ya I was really nervous heart pounding this is my first ball I'm use to my lil corns but I just tried to calm down and have confidence idk if he knew or not how nervous unwashed after hearing him hiss at me earlier but this time when I went to move him no hiss and Thnk god no strike he actually just was moving along my hand
