Thanks for the replies.
Mr. Cuddles made it through the night, but he felt a bit cold this morning.
For the lamp, should I only get one for one side or 2 (one for each side)? ETA: 75 watts is good enough, or should I get a 100 watt?
Also, where in Walmart is that thermometer usually found?
I also appreciate the specific advice about the hides. I wasn't sure how big to get, I saw one at the pet store and it seemed he would be too big to fit.
