I've shipped out successfully in low temps. We're talking 15-20 degrees on my side. I dropped the snake off as late as I could that way it would only be "exposed" for a few hours before shipping out. I ship hub to hub so really the snake shouldn't be outside of the building/plane for very long. I suggest shipping hub to hub if you are shipping in excessively hot or cold weather. I used a lot of insulation (thin newspaper shreds) and put the heat pack on the bottom rather than the lid of the box. I know other breeders have the same practice, that's where I learned from![]()
