About Advantage II Cat


Experience the Benefits of Advantage II
Help stop the misery of biting fleas with Advantage II. This vet-recommended topical formula works to kill adult fleas as well as flea larvae and eggs, so your cat can focus on you. It only needs to be applied once a month and is for cats and kittens 8 weeks of age or older.
Why Choose Advantage II?
Advantage II is waterproof, fragrance-free and kills fleas directly through contact. That means pesky fleas dont have to bite to perish. It kills fleas within 12 hours of the first application and can protect against further infestation for up to a month. Best of all, with Advantage II, you can stop multiple flea life stages, to effectively break the flea life cycle.


Help Break the Flea Life Cycle
Immature fleas in a pet's environment consist of around 95% of an infestation and can be nearly invisible to the naked eye. That's why Advantage II has two active ingredients that work to stop fleas. The first active ingredient kills adult fleas by targeting their nervous system, while the second works as an insect growth regulator that kills flea eggs and larvae.
Is Advantage II the Right Choice for Your Cat?
Whether your cat is a winter sunspot-stealer or a summer backyard explorer, an sunseeker or an outdoor enthusiast, choose Advantage II to help keep fleas from interrupting his favorite activities year-round. If you want to return the love to your cat, take care of him with flea prevention that works to kill the fleas you see and the ones you don't.
