I have the Frontline for kittens (drop form) that I was thinking of using on my ferrets. I don't have a whole lot of info. on the product, therefore, am hesitant to use it. What would be the correct dosage for ferrets and better yet...should I even use it on my guys? Norman weighs 4.0 lbs and Gizmo weighs 2 1/2 lbs. Any input would be appreciated. Thanks. Melanie and the gang! [Posted in FML issue 1934]
