Welcome to the forum. Sometimes a little patience is needed on responses. This is no ones job, everyone just doing it when they have time or even when they have interest in the post.

I agree with the suggestions that have been made concerning husbandry.

Maybe it is just me, but does that snake look thin to anyone else?
What are you feeding and how often?

(Maybe my I just have chubby balls.....)

I feed small mice every 5 days or so.. I've only had it a couple weeks.

How small are the mice you feed? pinkie, fuzzy, hopper, adult?

Unplug your UTH until you can get it regulated. They can get well over 140F.

On closer inspection, he does seem a little thin but not too much. I would bump up his food intake. You want there to be a noticeable buldge in his abdomen after he finishes his meal.
