One other quick tip. When using heat packs I always open them, stir them up, let them sit for 20 minutes or so to ensure they are heating and then wrap them in newspaper and tape the paper around the heat pack. I then tape the heat pack to one side (or one on each side of the box depending on temps) directly to the the Styrofoam. The last thing that you want is that heat pack getting jolted around and end up sitting right on top of the animal with nothing in between them then just a bag......
I would concur.
