I decided to try a mouse fuzzy. The good news is that although this girl may be small, there is nothing wrong with her feeding response. She struck the mouse very quickly and ate it with no problems at all. Good girl!

Going with Tim's line of thought that any food is better than getting a refusal if the snake is intimidated by a large meal, I think I'll give her a fuzzy at least one more time, and go from there.

Thanks for the advice everyone!
