Hi, I'm trying to sort out this mystery for you as well....
I looked back on your previous posts in regards to Laputa, and all the ups and downs.
The things that stand out to me are the water and the calcium dusting (or lack of calcium dusting). You have never used treated water (as in treated with a water conditioner and de-chlorinator))? Is that correct?
If I read correctly, you didn't start dusting with calcium until a couple weeks ago? You were gut loading your crickets previously, but not dusting. And she's been lethargic lately, and now not eating that much since beginning to dust with cal. I do believe she could be suffering from MBD, what was the vets recomendation other than the UV light? Any calcium shots or drops, special brand of calcium for her feeders?
And you have never used multi-vit? Get a mult i vitamin for her, and dust once per week. Follow Lynn's advice on feeding above.
Why did your vet not prescribe something for the pin worms? Only baytril? I'm confused by that. I'm also confused about the sequence of events in which she was tested and did get a clean fecal, and then later a bad fecal? She should be on a de-wormer for sure.
I think it would be a super good idea, because of the pin worms, to simplify her enclosure.
Use several layers of plain paper towel as substrate (not the substrate carpet your using, as it harbors bacteria and pin worms!)
Clean with very hot water all of her enclosure, water dish, and only one plant - every day! so important.
Get her meds for the worms, ask your vet tomorrow (even if you don't have a fecal by tomorrow for him/her to test). Dust her feeders and feed as lynn described, if she won't eat on her own. Dust with panacur according to the vet instructions.
This is gonna be a long haul, I'm sorry to say. You're gonna have to be patient and consistent in her care.
