That one looks like it's made from melame(sp) laminate. It's a popular building material for rack and cage systems. Heat would come from flexiwatt, either back or belly mounted, and controlled by a T-Stat.

For the money and trouble it would cost you to make one like that, you can just order one of these and have the best:
