Did you ask if they have ever come across the Nido Virus in their collection, or if their animals are tested for it ? I know some breeders just test their breeding animals, just to be safe.

Even if they do test, or claim to have never had it in their collection, at this point I would just add this test to the checkup. If he is no better by Wednesday and you take him in anyways, might as well get it all done.

Looking forward to hear what the breeder (and the partner in Germany) has to say about it all, incl. Yafe not improving just yet..

I still hold out hope he will just get better by Wednesday. How has he been looking today ?
