Advantage II Flea Control for Kittens is a topical, spot-on flea treatment applied directly to the skin at the base of the kitten's skull. The formula combines imidacloprid and pyriproxyfen, an insect growth regulator, to work on fleas at multiple life stages. Each tube contains a single monthly dose, and the package includes enough applicators for a two-month supply. Application involves parting the fur at the neck, placing the tip of the tube on the skin, and squeezing to release the entire contents in one spot. The product is intended for use on kittens weighing under 5 pounds and dries to a fragrance-free, water-resistant finish after 24 hours. It is intended for external use only and is not meant for kittens younger than 8 weeks of age.
