Snowball is approx 4 years old. He came to us in Nov. of 2004.  For some reason, he wouldn't adopt out.  He is the sweetest little guy and is so friendly to the other ferrets.  Snowball is now starting to show signs of being adrenal.  He has lost quite a bit of hair on his hind end and on his tail.  He is quite mellow compared to how he was when he first came in.  He sure is a wonderful little fuzzbutt.
