To Mary Allen: Based on postings from other folks in the past, I would suggest you look up insulinomas in the ferret FAQ and take your furrball to the vet. Dr. Williams may have more to say on this. To Matt: It sounds to me like your ferret may have a full-on upper respiratory infection with all the mucus and a visit to the vet for some antiobiotics would be indicated to prevent his condition from developing into pneumonia.
