The funny thing is that she'll stare at it, and then poke it with her nose, freak out, and curl into a ball for a minute or two. I had it hanging above her for a good 10 minutes before the mouse broke open. At that point i said screw it and got a live one. I'll keep trying with the frozen ones, but if i ever need anyone to watch her for a couple weeks or so, i hope i'll have her used to thawed ones by then. Most people don't enjoy watching snakes feed. I find it fascinating, personally.
