I would suggest you send MissT a PM.
She is not in the US but, can help with this better. Just reference her to this thread. :wink:
The fecal can usually be done by collecting a sample in a zip lock bag, bringing it down to the vet's and I could only guess their charge of ~30$ for the testing of it. If there is anything found that needs treatment they will usually require to see the dragon before prescribing any medications, this again is just a guess at ~50$. I can only guess as vets often have roughly the same prices but, they also vary.
