UPDATE: I found this e-mail from my (new) vet upon coming back home from work, regarding the stool pictures:
She does appear to have diarrhea or loose stool. There are many causes for this in frogs. Her fecal flotation was negative for parasites, but certain protozoa would be difficult to diagnose on normal fecal tests. Did they see any pinworm eggs at the previous veterinarian?
Potential causes of loose stool include: any cause of increased urination, protozoal infections, bacterial infections, viral infections, dietary changes.
Many of the causes could be treated with metronidazole. The previous veterinarian may be able to prescribe it for you. Legally, for me to be able to do so, I would need to examine her at some point before prescribing any drugs.
Looks like I got some calls to make tomorrow.
Well, I do feed her some thawed silversides (get 'em at Petsmart) every month. Haven't offered pinky mice in quite a while b/c they were expensive and not really very good nutritionally. As for her being stressed, I find it hard to believe if she was stressed she would even eat, which she has been doing throughout this quaratining/treatment process. Although I'm sure she hates the hospital cage as much as I do and I know she's happy with me about disinfecting it every day, which of course involves removing her from it daily. So. . .stress from the daily disinfectings. . .lack of dietary variety? I'll try some Dubias tonight and see what kind of waste that yields.
UPDATE:
Well the Dubias were a failure. She was there outside the water basin, took two grabs at the first roach and gave up trying to eat altogether. I don't get it. She used to be so fond of eating. Now she's been acting like a diva. Probably the hospital tank stress thing again. UGH!
