UPDATE
 
So, I was finally able to submit a stool sample to Juliet's vet for a PCR wide spectrum test. The results are negative for Tritricomonas, which I find unfortunate, because if it were positive the medicine would have potentially cleared it up. The results did test positive for Clostridium and Corona virus. The vet said corona virus is common in cats, and Clostredium is normally found in dogs, the medicine for it however is daunting - 3 week course of horrible tasting medicine. He suggested we wait and see if she can outgrow it and/or try switching her chicken-based diet to rabbit or duck. He also said her high strung personality may be a cause for her inability to fight off these diseases, and to try to work with her to try and lower her stress level. So that's where we're at right now, I will continue perusing a treatment in any possible way for her, research etc. If anyone has any experience with the mentioned viruses, please let me know. Any and all suggestions are welcome.
