Lin, might there have been lymphoma at the base of the problems for the three ferrets? There IS a form of lymphoma that ferrets get which appears to have a silent viral trigger 2 or 3 years before the lymphoma rears its head. It causes clumps of such ills. You can find more about it in: <http://www.afip.org/consultation/vetpath/ferrets/PDF/Lymphoma_Ferrets.pdf> That section begins with the final paragraph of the first column of page 2.
