I just got back a short time ago from taking Snyder to see the doc. First off, I can stop referring to her as "s/he", because she's female. Second, her weight is 110g, obviously light for her 22" length. Third, Dr. Tyler didn't have a lot of hopeful things to say for Snyder.
She's started exhibiting neuro symptoms, such as not immediately righting herself when turned upside down. She's still dehydrated, though her spine isn't as prominent as when I got her. The doc administered sub-cue electrolyte fluids and a dose of Panacur (in case, didn't get a fecal sample). She did say that Snyder is tick-free (I hadn't seen any), appears now to be mite-free as well, and that the habitat sounds good.
She recommended upping the temp in the warm end to 90+, soaking her for at least an hour a day, and force-feeding a pinky tomorrow and mid-week. She (doc) gave Snyder better than even odds of survival, but that's about it. I doubt Snyder's chances would even be that good if it weren't for the good folks here and elsewhere with all the useful info, so thanks, and think good thoughts for Snyder.
