Adelita's settling in well and the IR temp gun arrived tonight. The floor of the cool side was ~79 degrees, the middle zone was ~83 degrees, and her basking spot was ~86-87 degrees under the heat projector (in 86 degree night "drop" mode - I have it set to 88 degrees during the day). Based on the ambient temps in the room, it seems as though the digital thermometer is reasonably accurate. We had a bit of a heat wave by me today and the ambient temp in Adelita's room rose to around 80 degrees when the AC unit had a bit of trouble keeping up. Not that she minded- she was actually trying to climb up the digital thermometer's cord for the first time since her first day home. She definitely seems to like temps in the ranges you mentioned, dakski. Her viv is actually maintaining a relatively stable temperature gradient in that range with a humidity of 62-67%, so I'm quite happy with where things are now. I may have to keep an eye on that humidity, though.
My big debate right now is when to offer her her first meal with me. Her last meal was a live hopper mouse on 2 September, so it's getting close to feeding time for her. I've only been able to get frozen hopper mice, though, and I haven't been able to find anyone with live hoppers around me. I'm a bit worried that I'd be asking too much of her for first meal home to be her transition to f/t. I'm also not sure if I want to try and feed her Friday (her fifth day home and possibly too soon), Sunday night (after being home for a week), or Monday morning (two weeks after her last meal - a bit long for a baby boa). She seems to be settling in and possibly ready for a feeding attempt on Friday, but I'm not sure how to judge her "readiness."
