They can cause sever burns. Buy a UTH they make ones that will stick on the bottom of the cage. . On the outside of the cage so the snake cant come into contact. Also buy a thermostat take the prob for that an stuff it between the cage and the uth, it will keep it from over heating. Tinker with the heat until you reach the hot spot you want, easist way I find to check is one of the temp guns. But if you dont have one or break them all the time like medigital thermometers on the hot an cold will help you get everything dialed in.
