I doubt I'll be able to help, but a few questions that might let someone else be able to...

1) Did she soak in the chlorinated water? If so, was her behavior pretty much the same prior? I'm having trouble finding out much about the time frame that it takes for chlorinated water to kill amphibians, but I'm skeptical about it being due to chlorine toxicity.

2) I'm assuming, if you had her this long, the vitamin situation is fine. The symptoms still kind of remind me of what I've read about metabolic bone disease, though. Can you briefly describe what and how often you've been dusting?

3) You keep mentioning the cold. About what temp is her cage? Just curious.

4) How fat is she? Does she still have some fat left on her, or is she pretty much wasted away with a clearly visible pelvis? This isn't really a symptom, but if she is pretty wasted, more dire action like force feeding may end up being necessary. If she's a fat little thing, it can wait a while.

I feel obligated to mention people like Dr. Frye (very helpful, talked with him when I was having trouble last year) who will give a free email consultation. He's not legally allowed to give advice if you caught a native species, so you might not mention that if it applies to you. Something to keep in mind. dr.frye.vetatmilan@gmail.com

While you probably know this already, I want to say it to be clear. As the poor girl IS under the weather, avoid bothering her as much as possible, even if you just want to help by giving her food. Only do necessary interactions. The effect stress can have on sick animals, especially small ones, is significant.

For this reason, I wouldn't recommend making a quarantine tank. They're a trade off between sterility and, usually, increased stress. I never saw my poor girl as upset as when I banished her to the 10 gallon hospital tank. They have their uses, but I don't think it would benefit Lola in this particular case.

I hope things improve.
