Thanks! I have been playing with a good, snug, warm set up and if I fold a towel into the plastic tub, I can put the heat packs under a fold of the towel and then put her and the pillow case in and she will have a nice soft, sung, toasty box. I'm going to crack open a few heat packs and just put them in there for a dry run and check the temp to see how many I should use. I am in NorCal, it's been in the low 50sF during the day lately. Too cold for ball pythons, so I will make sure the air doesn't get her and she has a nice warm car waiting for her.![]()
