Things to look for when buying from Private Owner

[Wrath]

Hiya,

I am going to look at a Ball Python about an hour's drive away tomorrow. I want to make sure that she is in good health before I make a decision....but I wanted to know if I'm missing anything here.

Check:
eyes, nostrils, mouth clear of guck and mucous
for mites and skin free of wounds

What else?? I would think I would be able to determine health easily, but I want to make sure that I make a good assessment.

If she is not up to par, I will just get a CB hatchling from a petstore, but I did not want this one to go homeless if she needs a home and I have one to give....
