Thanks for the replies guys. I knew that the lack of a thermostat was a problem and I plan to remedy that right away as soon as my classes (I'm a student and my boyfriend works full time) finish for the day. So she is due to be fed on Sunday, should I perhaps wait till the week after that to feed or attempt to feed her in a few days?

Also, yes, the rats are frozen small ones. They gave us two sizes, 6 rats she can eat and 4 that will be her next step up. In the two years they've had her she only bit once and that was when they were moving her to feed.

Shes a a very interesting girl. Absolutely gorgeous and very active. She's honestly the perfect snake for me and my boyfriend, I just want to make sure that her enclosure supports her well. The last thing I want is for her to get sick. I believe she had mites once due to a poor quality substrate and the old owners got rid of those and now have mite spray that they gave to us.
