Puddy was on Viralys after her surgery but for the life of me I can't remember why. I do remember, though, that she hated it. But then, she hates everything. Calicos and orangies are tough cookies so I had to be stern w/her to get her meds into her. And if that meant isolating her, that's what I did. You may have to enclose Michael in a separate room until he becomes more cooperative. I wish I could be more helpful.
