Advocate is applied to cats, ferrets and dogs from pre-filled pipettes. These are small plastic droppers, available in different sizes depending on the size of the animal, which are filled with the correct amount of Advocate for one treatment. The content of a full pipette is applied onto the animal’s skin, after parting the fur. In cats and ferrets, the product is applied to the animal’s neck at the base of the skull.
