Seriously, I have never known a snake react in such a way. I have an albino chequered garter, adn she is honestly the most funny little snake I have ever owned:
If you ever get a chance of a CB garter (proven feeder) get one. Cracking cheap little snakes.
Feeding time is funny too, straight out as soon as she smells mouse, then grabs and eats infront of you. No coil though, apparently they don't
