Does anyone know if it's safe to use Advantage II on ferrets? I know Advantage I, Frontline and Revolution were 'relatively' safe, but don't know about Advantage II. Please, I'm not looking to get slammed here for anything. I just need to know what to be able to tell those people who ask and are going to use the drops no matter what.
