Grandson's Ball Python has survived his stay with Grandma, and now it's time to drive him in my little suv to his new home in Chicago next week. What is the best way to keep him in healthy range of temps? Given normal late July temps I'll run AC in the car for the 9 or 10 hr (no overnight) trip. He just finished a good molt and has one full meal in his belly, 5 days before trip. Does he need a heat pack? I'm concerned about overheating at stops and chilling the rest of the time.
