I fed her today, 2 f/t fuzzies. I only had to leave them on top of the hide for her to come out and grab the first one. It took her a little while to find the second mouse - maybe it had "cooled off" too much and she was having trouble tracking it down - but once she found it, it was gone!
Now that I know how to get her out, I'll make it easier for her next time and wait for her to come out, then start moving the mice around so she can spot them quicker.
And possibly for the first time ever, the boa ate a f/t too 8-) Guess it's time to make some room in the freezer; looks like I can now stock up on these mice.
