Well, tonight was a first. Bonnie, my female hoggie, decided that my index finger looked a lot like her hopper mice, so she decided to go for the kill.
She gnawed on the side of my finger for about 3 minutes before I could get her off. I tried pouring cold water to get her to let go (read that somewhere, can't remember where) without luck. I ended up gently taking the tip of my snake hook and wedged it between her upper jaw and my finger. That did the trick. While I wouldn't normally recommend that for the snake's safety, I was very careful and gentle. I wasn't going to let her gnaw on me for the next 10 minutes, especially since she was desperately trying to get my whole finger down her gullet.
We'll see if my opinion on the venomous nature of hogenose bites changes in the next few days. I'll keep you all updated.
