Thanks again.

With my vet, I do get a discount, since I work next door. He's a decent vet, he just isn't always super up-to-date on exotics. He's willing to work with me though, which is more than I can say for most vets. He even understands that these rats are breeders to make feeders, etc, so tries to take into account they are eventually supposed to be food animals, instead of insisting they be pets and not considering which drugs are administered.

I appreciate the link to dosing/meds on rats. I'm not sure if any of these rats have been anywhere near any colonies in Orlando, but of course, it's entirely possible, since Orlando is not far at all.

If it's Sendai, is there a way to diagnose other than just symptoms, and what's the prognosis overall? Is there a write-up somewhere about it?

With the Duramycin 10, I have to dump/wash out the bottles each day, right? With the 8 oz bottles, they did not drink all of it(some did) and I'm dumping whatever was left and re-mixing and re-filling. The whole bag of med at TractorSupply only cost about $5 btw.

NO dead rats today. I'd also like to say, only adult rats have died. None of the babies, none of the young ones, not one of the new rats. Only the older breeder rats. I still have pregnant rats that look due, litters of pinkies and I weaned a litter of 10, with another litter of 15 that's getting closer to weaning. Does this sort of thing usually kill adults instead of babies?

There is some sneezing still, but no rats look horrible. I'm going to dose the same as yesterday. Duramycin in water bottles and then certain ones are getting the double Baytril/Doxy doses(in yogurt).
