My girl Flame is like this. As soon as she smells a rat, she is waiting in her enclosure to strike at any moment! Even if she just ate, (when I am feeding another of the snakes.) As soon as I slide open the tub, I have to instantly offer the rat on tongs, if I give her even a second, she leaps out and starts striking at anything warm! She is voracious.I am SO HAPPY about it, as she has never refused a meal, and is growing rapidly.
Also, she has never struck at me defensibly and my kids can even hold her, I just have be very cautious if there is any rodent odor at all around! THEN she turns into a killer.
