I am using a Hydrofarm Jump Start thermostat. Of course, I prefer that he doesn't come into contact with the plastic floor just in case I am very aware that he could still find his way into direct contact, but with a combo of a thermostat and the paper towels, I don't think a burn is very likely. And the reason I don't want to use all paper towels is because then he could easily find his way under them, and possibly get burned.
