I do not have a scale. And he hasn't ate for me yet, but he looked more interested in it last time I tried. He hasn't gotten any thinner and he is still active. I'm just worried about him being cold or something. When I look at my probed thermometer about a inch off the ground hot side it says like 83-88 normally. But when I measure ground temp with my gun it shows 88-100 depending on how close I measure to the direct rays. I know 83-88 is cold but his belly temp/ ground temp is perfect. Am I doing that right? And he is basking in the day. It's only been three days now on the basking though. But he is there right now, just chillin.
