To Cindy Sooy:

   Cindy - subcutaneous tumors are very common in ferrets and may arise
quickly.  The key here is that over 95% are benign.

   Ferrets rarely get calcium depostis, and then only in areas of previous
vaccinations.  They also rarely get fibrosarcoma - sarcomas (malignant tumors
of non-epidermal origin) that I have seen are hemangiosarcoma (a tumor of blood
vessels) and neurofibrosarcoma (a tumor of nerves) - but both of these are
low-grade, easily removed, and I have never seen metastasis.

   That's the ticket!!!
