Proheart 6 is the new heartworm product from Ft Dodge.  It is an injectable
product that prevents heartworms for 6 months.  It contains moxidectin,
which is similiar to ivermectin.  The company has not done any work with
cats or ferrets at this time.  It is a good product for dogs, but we do
not know about its use in ferrets yet.

PS  Proheart has been out in Australia for a while now, so even though
    it is a new product here it has been used down under for a while.
