Dear anonymous poster,
 
I, too, am a fugitive ferret-owner.  Fortunately, vets are not required
to report treating ferrets, and there are several great websites
dedicated to those who share our situation.  One of them has a handy
list of ferret-friendly vets, many of whom are absolutely incredible.

My best, and best wishes to your little ones...
