On the subject of quarantine, I should also add that I'm a year from my bachelors in microbiology, and have a high-powered microscope at my house. I can, within a week or so, rule out most intestinal parasites, fungal infections, or mites of the skin. I still keep the animals quarantined for about 60 days to rule out viral or bacterial infections, but I'm making some additions to my home lab over the summer that will allow me to do a bacterial work-up on all of my animals as well.
