>heartworm is a danger to ferrets, I have learned, maybe i forgot but >this is a problem considering all the mosquitos we have this year.... >any suggestions? comments? A couple of studies (not big ones) concluded that for protection from heartworm, ferrets need a minimum of 18 mg of Selemectin monthly during mosquito season. So I use 1/2 of a vial of Revolution per ferret. The Revolution for cats 5-15 lbs. has 45 mg of Selemectin per vial.
