I've only been struck at once, and it was admittedly my own fault. My ball was pre-shed and wasn't quite showing signs. It'd been about two days before her last meal, so I felt confident in handling her, and she'd left urates in her enclosure fairly close to the hide. So I figured I'd take her out, clean up her mess real quick, and set her back in good as new. I reached in, ran my hand along her back the way I did every other time I'd handled her, but this time she hissed at me. I ignored it, putting the need to have the cage cleaned above her not wanting to be handled, figuring she'd go back to her normal docile behavior when I took her out of her cage. And that's when she struck me. Just once. I didn't even feel anything at the time, because she was maybe six months old and still fairly small. As I was putting her back, I happened to notice the small scratches from where her fangs had scratched the first few layers of skin on the back of my hand. Nothing major. I chalked it up to it being her way of telling me she didn't want to be messed with. And the evidence was the single shed I found in her cage a couple of days later.
