I don't think there's been any deaths, although I did read a post from someone on here saying that a man fell down the stairs, got knocked out, and died because the ball python got scared and constricted on his neck.
We put ours around our necks. They've never gotten too tight, and when they do get uncomfortable for us we either readjust them or wrap them around our arm instead.
If you aren't comfortable with it, don't do it. I have very very long hair and one of our BP's loves to play in it. Another one will wrap himself loosely around our necks and hang like a necklace. The third one would rather be a bracelet.
It's all what your comfortable with.![]()
