Good news! Looks like raising the temp did the trick. He came out for a little bit just now. He ate some and then went back inside. I bought a thermometer and stuck it inside. It is 70 degrees by the door, which is the coldest part. I meant to hang the thermometer up but I walked away for a few minutes and when I came back Pascual had sat on it and cracked it! it's definitely broken because it reads 120 degrees outside. So annoyed... Just bought it a few hours ago, but at the same time I couldn't help but laugh. I did some shopping for that particular heater but there wasn't much of a selection at my Wal-Mart or hardware stores. I'll keep my eye out. Next week my boyfriend and I are planning on building a house per Tom's specs. Thanks for all the advice, everyone! Got me through this lil cold snap crisis.
