has anyone dealt with this tritrichomonas? I have a 20 month old Persian. She is healthy otherwise. Treated her for this last summer. She was clear for a few month and now it is back. There is some controversy about the ronidazole used to treat it. Some articles say it will resolve on its own. I plan on taking her back to the vet. She recognized tis problem long before it was considered a problem. Betsy came from a very reputable breeder who has no other cats that have tested positive for this. We have one other Persian from the same breeder and no problems at all. thanks
