Biggest Husbandry Mistake?

[Bogertophis]

Great stories. I do wonder if there's ever been someone caught by a hot fang through an air hole.

Probably so, but when I kept rattlesnakes (for 20 years safely), I too thought about that & modified the Neodesha cages that I used for giving programs with them so that
no one could accidentally put their hand on an air vent & get "nailed". I added "fang guards", little cages made of perforated metal about 1" deep so there was NO chance
that any fangs could go all the way thru the covered vents. For those unfamiliar with Neodesha cages, they had sloping plate-glass sliders on the front that I could easily
lock in place, making the travel & programs I did with them quite safe. You have to think of EVERYTHING when you keep hots, and especially when you share them for
education.
