Well it's just for overnight. Someone in the morning would know if I did something wrong I guess. But I'm almost sure what we had back there was thermometer and not a thermostat. Pretty sure it's the one I had linked. It's not on carpet, but aspen bedding. There's also a log hideout in there.
But yeah, I don't even think we carry thermostats at Petsmart. I think that's why we only sell heating pads that are only suppose to raise the temp 5-10 degrees above room temperature.
