She won't eat anything

Awww.. she sounds like a sweetheart, too. Let us know how it goes with the guppies. Just curious, and I'm sorry if you've already said, but how big is she?

It may be getting near the time to consider force-feeding her, Lori. This isn't necessarily such a trauma. For a small snake you need to use (obviously) small food items, but they need to be firm enough so they don't just fall apart in your hands. Pinky or fuzzy legs and tails are good for this.
Sometimes it's enough just to push the food against the side of the snakes' mouth, this can often trigger a feeding response.
The best of luck, Lori. Please keep us informed.
