Wondering what else to get

[The Serpent Merchant]

Just to clarify, you're using a reptile-specific UTH (heating pad) right? Not a human one?

I would suggest that you use Flexwatt, it is cheaper and I have found that it works better.

You can get it from a website called reptile basics

here is a link, and another link that will give you all of the information you will ever need on flexwatt
