I have been mitten by my 7+ ft boa. I didn't even know it happened till it was over. I was surprised how little damaged she did. Sure it was bloody and all but in the end you can't tell anything ever happened.
I have scars from cat scratches.
But the psychology of being bit by a snake is much greater than being scratched by a cat.
All that being said to say that, it is perfectly understandable to try and protect yourself but an animal known for biting.
