He seemed pretty sure when he said she was eating prekilled rat pups, but I guess it's unlikely he just knew that snake off the top of his head since he had other pastel babies/juvies with him... He could have just as well been lying :/ Now I'm really nervous to see if she'll eat this coming weekend... I guess I'd better pick up some mice in case she doesn't take rats.
I'll definitely be pickier the next time I go to an expo, whether it's for a snake or a lizard, because I know this won't be the last time. I just hope this time works out okay, because she's a really sweet snake.
@bumblee1028: Thank you! I hope so too, haha.
