I have a total of about 12 hours of driving with a stop-over at a relative's house about half-way. One vehicle is being driven with our dog & cat in it. The other is being towed behind the moving truck. Is it ok to put the snake in his aquarium in the back seat of the car being towed? Will it get too hot even if the windows are cracked? Would it be better to put him in a smaller enclosure in the car that is being driven? I have never moved this far with him.
