An extensive list of ferret clubs, breeders, organizations, vets and
catalogs is maintained by STAR*Ferrets and is available on the World
Wide Web at 
<http://www.ferretcentral.org/for-others/database.html>.

It is also available from a list server.  Send email to
<listserv@cunyvm.cuny.edu>
with the line
SEND FERRET DATABASE
in the body.  Note that the file is rather long, which may give some
mailers problems.

The American Ferret Association (AFA) also maintains a list of
shelters, at <http://www.ferret.org/afashltr.htm>, and a local ferret
club may know about one not on either of the lists.
