I used to have some links to online stores where you could purchase Advantage and Program. Does anyone know where I can find those links/URLs again? Also, since I have 11 ferrets, it's much more economical for me to purchase Advantage in the larger sizes. What is the dosage/amount to use on a per pound basis for ferrets? Thanks!
