A Cat Sitting In The Sun

Advantage II for Cats is a monthly flea and tick medication that keeps your cat safe from pests. But how does it work? Find out all about Advantage II here.

Many of us apply our cat’s monthly flea treatment without truly understanding how it works. We just assume that it will do it’s job -- and that’s true -- but wouldn’t it be nice to know what that job entails? With the knowledge on hand, you’ll feel assured that your cat is free of fleas, and you’ll be prepared to keep it that way.

Let’s explore how Advantage II for Cats works.

What Is Advantage II for Cats?

Advantage II is a waterproof, once-a-month topical treatment that kills fleas in all life stages. It not only kills flea eggs and larvae and thus prevents them from developing and reproducing, it also kills adult fleas on contact, so they do not need to bite your cat in order to die.

Advantage II for Cats protects your cat for up to a month.

Who Is Advantage II for Cats For?

Advantage II is safe to use on cats and kittens 8 weeks of age and older. It should not be used on dogs.

How Does Advantage II for Cats Work?

Advantage II is applied directly onto the skin at the base of the cat’s skull. The product is then absorbed into the skin and becomes part of the sebaceous system. The sebaceous system produces body oils, and the oils work to evenly distribute the product over the cat’s body.

Advantage II for Cats contains two active ingredients:

  • Imidacloprid is an insect neurotoxin that attacks the flea’s central nervous system, causing paralysis and ultimately death. The great thing about this ingredient is that it doesn’t kill the flea right away -- it lets it return to its nest and infect other fleas first.

  • Pyriproxyfen is an Insect Growth Regulator (IGR) that works with Imidacloprid to kill fleas and stop the development of flea eggs and larvae.

Advantage II for Cats kills fleas within 12 hours and reinfesting fleas within 2 hours.

Having and getting rid of fleas can be an unpleasant ordeal for both you and your cat. Make sure it never comes up by protecting your cat every month.
