If you set them up without a hotspot, you need to maintain a pretty rock solid ambient room temperature. I like 82 degrees.
Hot spots are 86 to 87 degrees if provided.
Id make sure your animal has a perfect setup with ZERO Stress and zero handling for at least a few weeks.
Do your research on how much to be feeding and after you get a few meals in her would be a good time to start your handling sessions then. A few seconds at first then working your way up to 5-10 minutes.
