That was the state I got him at; what he was left at my house with. It's now at 94 at the highest. I corrected it immediately both when I noticed the heat that was being given off, and when I noticed the heat difference between the two hides.

A regular dimmer wouldn't change the heat retention difference between wood and plastic if kept at the same strength for each. A probed thermostat would.

The plastic got significantly warmer than the wood when next to an equal heat source. I figured someone may find that informative. I understand the chances of worse outcomes to obtain that lesson. Luckily, it was corrected in a two hour time span.
