Thanks for the suggestions, guys. I'll shoot her this evening when I get home from work and post.
They fed her live, and I did this past weekend, but I worry about the snake getting bit. The previous owners said they would 'stun' the rat by smacking it on the head, I tried that but it didn't seem to work. Is there a 'best technique' for killing the food item?
She's a little less big around than my wrist, so I got a rat that was about that size, moved her to a plastic container, and she fed with no problems, but seemed to have difficulty finding the head, first she tried the foot, then the back, and finally, after some repositioning on my part, she found the head and went to it.
Temperatures are something I worry about, as my house is kinda cold. I have a UTH, but it doesn't seem very warm, and I couldn't find a quality thermometer with probes locally.
