Thanks for the info! I just fed her a pinkie mouse, and she was happy to take it... but she wouldn't take it from the tongs, just when it fell to the ground. I may have to reconsider a feeding tub, since I don't want her ingesting the substrate (tonight I cleared a spot when she started moving it around). She did start looking for a second mouse the second she finished, so next week I'll definitely give her two mice. Here are a few shots from the feeding:

She tried to eat it sideways at first, LOL.
