Might not be a bad idea at all. Many folks end up with some nice animals via private sales or situations like this. Since this is a local situation, I would ask if you might be able to go over there one evening and watch it eat. That isn't something most people think to do, or aren't able to do, but this situation is a bit different and it might be possible. If she'll let you, do it. If she won't, I would begin to wonder a tad bit.
When you are able to see the snake in person, look at its condition closely. Make sure it appears to have good body weight, doesn't have stuck shed, and the vent is clean and clear. When you handle the snake, it should grip you firmly and its body should feel muscular, not flabby but not hard either. Gently use a Q-tip and, using the stick sideways (think of a dog holding a bone), gently open the mouth and check for bubbles and/or a cheesy-like substance. If you see that, stear 100% clear - that's a sure sign of an RI. Also look at the enclosure - is it clean and is the water fresh looking? What is the heat source and how is it being controlled? This will tell you how the animal has been cared for. Look the snake over VERY carefully around the eyes, under the chin, and around the heat pits for any signs of teeny tiny black dots - these are snake mites and you certainly don't want these buggers.
If this vet clinic does treat snakes, than this receptionist probably knows how to properly care for a Ball Python. You can't work at a place and not pick up a few things or two or three. As such, I would expect you to find a snake that is in reasonably good condition. I think you should go take a look.![]()
