I'm in Waco, there are TWO good exotics vets here. Why not make the drive or let me take the snake for awhile until she's recovered.

There is also Dr. Carpino in Temple, you can always see if she'll look at snakes(she's a bird vet).

That snake needs to be seen by a vet. She doesn't need a bigger cage, she doesn't need to be fussed with. She needs proper husbandry and a 50gallon tank in winter isn't going to cut it.

I have extra tubs if you want one, as well as some heat tape and rheostats.

I suggest getting her into a much smaller enclosure, bumping up the heat and humidity(and measuring it properly with a digital thermometer) and getting her seen by a vet as soon as possible. If you cannot afford that, then let me know and I can. I can always meet you in Lorena or I can just go all the way to Temple.
