Ultimate Guide to Advantage II for Cats

Meet the Flea Life De-Cycler: Advantage II for Cats!

Advantage II for Cats is an FDA-approved, veterinarian-recommended, waterproof topical solution that protects your cats from flea infestation by uniquely breaking the flea's life cycle. One easy-to-use topical monthly application lasts for 30 days. The medication kills all fleas within 12 hours through contact with the cat's skin and hair.

How does Advantage II for Cats work?

Advantage II for Cats is a medication with two active ingredients and insecticides - Imidacloprid and Priproxyfen.

Imidacloprid is a systemic insecticide that binds to invertebrates' receptors of insect nerve cells. The insecticide disrupts, damages, and paralyzes the insect's central nervous system (CNS) on contact and the fleas eventually die.

The second active ingredient, Pyriproxyfen, is an insecticide and Insect Growth Regulator (IGR) that specifically breaks the flea life cycle by preventing normal growth in immature fleas in becoming adult fleas and disrupting proper hatching of flea eggs.

How is Advantage II for Cats administered?

Advantage II for Cats is administered topically once a month and lasts for the next 30 days. Slowly apply the entire solution contents from the applicator tube (i.e., pipette) in one spot directly on their skin between the shoulder blades.

The dosage amounts that are available depend on the size, weight, and age of your cat. The three strengths and colored boxes that are available are the green Kitten box for those that weigh 2 to 5 lbs., the orange Small Cat box for those that weigh 5 to 9 lbs., and the purple Large Cat box for those that weigh 9 lbs. and up.

Advantage II for Cats kills all life stages of fleas within 12 hours after application, and prevents the development of flea growth after just 2 hours!

Before use of the medical product, inform your veterinarian of all treatments and medications that your cat is taking, due to potentially negative interaction with Advantage II for Cats.
