I would strongly suggest people stay away from them, especially for animals as small as ferrets. Although Frontline and Advantage are not specifically recommended for ferrets, at this point a lot of vets and ferret folks have used them safely. A very tiny amount goes a long way--you only use a drop. Now that flea season is upon us, please be careful not to poison your ferrets, you, your home, your lawn, etc. with poisons. Ronnie in Mass.
