I currently have 6 ferrets all with Marshall tattoos.
 
- Female Marshall silver mitt born 12/1999-bought from store, diagnosed
  with Juvenile Lymphoma.
 
- Male Marshall dark sable born 12/1999-bought from store healthy.
 
- Male Marshall dark sable born 12/1998-bought from store healthy.
 
- Female believed to be a Marshall (has tattoos) butterscotch given to me
  born 12/1998-healthy.
 
- Female believed to be a Marshall (tattoos) sterling given to me born
  11/1997-healthy
 
- Male believed to be a Marshall (tattoo) sable given to me born
  1/1995-healthy
 
All of my ferrets have been really healthy no problems other than the
juvenile lymphoma and she is doing great.  My Old Timer at five years has
experienced some hair thinning but it is not Adrenal Disease.
 
Thanks and hope this helps,
Candi
