Ok, so I was waiting to see what would happen before posting so here is what happened.

I ended up having a good conversation with the guy who was looking at the snake. After I was able to convince him that snakes are not iguanas things went pretty smoothly. I explained the need for a thermostat and heating pad and digital thermometer. He seemed to understand and I had some laying around and offered them to him. He said it sounded like a plan and he would contact me over the weekend to come pick everything up.

Then of course I never heard from him again. So, he continued to be an oddly disinterested guy, he sounded excited on the phone so still seems weird.

Thanks all for your help!
