Your setup is lovely, the fact that she may be ill is almost certainly not a result of that. In fact, she very well could have been coming down with it when you purchased her. Who knows? You've done a wonderful job with the setup, and the fact that there are lots of housing options is irrelevant if yours works for your animal. Kudos to you for putting in the effort. But purchasing an animal also has associated vet costs at one point or another. In fact, after spending quite a lot of money on the setup for my first snake, I ended up spending hundreds on vet bills for a RI that she must have already had, and all in the first two months. It happens. If it is not a cost you are comfortable with, then don't purchase an animal. After a month, most shops and breeders will not take the animal back. I'm not trying to be inflammatory, I'm just being honest.
On a forum, you will always receive varying opinions. I would perhaps give a little more weight to those with more experience, over others, but that is my opinion. At any rate, you will do as you wish regardless of the advice offered. If you do not want the responses, don't ask the question. Simple as that. And I do not appreciate being ranted at when I've offered advice that was asked for. As such, you will receive no more from me.
Best of luck with your snake.
