I am thinking about getting a heating pad with a car adapter for my Leopards travels. I live in Chicago, travel a lot to Northern Michigan Do you think a heating pad with a blanket over it in a plastic travel box with a lid and a hide house with some substrate would be a suitable way to keep him warm. He is small yet only 8-9 months. This idea is only for the car ride. I will have a small yet complete set up for when we arrive at our destination. I know they are a little expensive, but if it will work, i don't care about the price. Plus the one I found is on sale for $49.99 from $70.+.
