Advantage II Flea Control Medium Cats 5-9 lbs

Keep your cat and your home safe from fleas with Advantage II Medium Cats 5-9 pounds. Formulated for cats eight weeks and older and weighing 5 - 9 pounds, Advantage II kills fleas within hours of application and protects against future flea infestations.

The Importance of Flea Protection

Protecting your cat from fleas is essential for health and well-being. Flea bites not only cause discomfort for your cat, but also can cause irritation that can lead to skin infections. In some cases, flea bites can lead to allergic skin reactions, or even result in the transmission of other disease-causing organisms, such as tapeworms.

Kills Fleas Within Hours of Application

Millions of pet owners have found success against fleas with Advantage Topical Solution. Its successor, Advantage II, kills even more flea life stages. Advantage II kills fleas through contact, so they don't even have to bite to be destroyed. This helps reduce the risk of secondary problems, such as flea-allergy dermatitis.

The active ingredient in Advantage II, imidacloprid, acts on the nervous system of the flea to cause paralysis and subsequent death. Advantage II destroys the fleas living on your cat within 12 hours of application, providing quick relief for your pet. Reinfesting fleas (newly hatched fleas jumping back on your cat) are killed within two hours of application, so if your pet picks up fleas from another animal or infested environment, those fleas will be killed as well.

Flea Cycle
The adult fleas you see are only a small percentage of the infestation.View larger.
Protects Against Further Flea Infestations

If you are already dealing with a flea infestation, you may only be aware of the adult fleas, which comprise a mere 5 percent of the full infestation. The flea eggs, larvae, and pupae make up the other 95 percent of the infestation and can be virtually invisible to the eye. The insect growth regulator contained in Advantage II effectively breaks the flea life cycle at multiple stages to treat existing infestations and prevent future infestations. Each dose of Advantage II provides protection for an entire month.

Waterproof Formula

Advantage II is waterproof, so there's no need to reapply after your cat has a bath or goes out in the rain. Studies show that cats are still protected against fleas after exposure to water, though for best results, cats treated with Advantage II should be bathed with a non-detergent shampoo.

Usage Info

How to Apply

Applying Advantage II to your cat is a fast and easy process. First, remove the applicator tube from its packaging and use scissors to peel down the foil. Next, hold the applicator tube in an upright position and pull the cap off the tube. Use the upturned cap to break the protective seal, and you're ready for application.

How to apply

Part your cat's hair on the back of the neck at the base of the skull until the skin is visible, then place the tip of the tube on the skin and gently squeeze out the entire solution. Placing the treatment here minimizes the cat's ability to lick the product, which is bitter tasting and may cause salivation for a short time if licked after it is applied. Do not get this product in your cat's eyes or mouth. Dispose of the container and do not reuse or refill. Do not empty unused product in any indoor or outdoor drain.

For optimal control and prevention of parasites, use Advantage II every month. Do not use this product on any animals other than cats.

Length of Effectiveness

Under normal conditions, Advantage II is effective for one month. However, in cases of severe flea infestation, retreatment may be necessary earlier than four weeks. Do not retreat more often than once every 14 days. After flea control is attained, return to a monthly retreatment schedule.


See back panel for first aid. For instructions on storage and disposal, see supplemental labeling inside package.

Keep out of reach of children.



How long does it take to kill all fleas after the first application on an animal that has fleas?

24 hours to zero fleas counted.

Does it kill ticks as well as fleas?

No, there is no tick activity at all. This product is highly specific for fleas.

Activity against parasites other than fleas and ticks?

Fleas only.

How long does a single application last?

One month.

How soon after bathing can it be applied?

As soon as the pet is dry.

Does it wash off?

Yes, this product washes off completely with a degreasing shampoo. It can withstand one bath between applications and swimming once a week between applications, but no more.

Flea-killing active ingredient?


How young can the cat be for application?

Eight weeks.

Approved for use in pregnant or nursing mother cats?

Not in this country, but approved in other countries (US EPA does not recognize testing done for other countries and testing in pregnancy/lactation has not been done in the US).

Does the pet need a veterinarian office call in the last year to get the product?

No, this is an insecticide, not a drug. However, the manufacturer sells its product for resale only through veterinarians, so proper usage, etc. can be explained.

Is the product safe for use on sick, elderly, or debilitated patients?

Product should be safe for such use provided the patient is receiving veterinary care. Otherwise, if the pet is inactive or hospitalized in a cage, the product may not spread around the body as rapidly as usual.




Imidacloprid is an ectoparasiticide, an antiparasitic agent that targets parasites living primarily on the surface of a host. Chemically classified as a chloronicotinyl nitroguanidine, imidacloprid inhibits neurotransmitter transmission in insects, resulting in paralysis and death.


Imidacloprid exhibits both adulticide and larvicidal flea efficacy; it not only kills adult fleas and larvae on your pet, but it also kills larval stages in your pet's immediate surroundings.

Main Purpose

To kill fleas at all stages of their life cycles and stop them from being able to move or feed.


Pyriproxyfen, the added compound in Advantage II, is a pyridine-based pesticide. A juvenile hormone analog, it interferes with the hormone signaling of growing insects, so that insects in immature stages are unable to mature. Additionally, a female insect that touches the toxin will produce eggs that will not hatch.


Pyriproxyfen provides an added layer of protection for pets and their surroundings. It interrupts the flea life cycle at multiple stages, halting the growth and development of insect eggs and larvae and preventing reinfestation.

Main Purpose

To prevent flea eggs from hatching and larvae from growing.

Love the low price! Kill the fleas! Fast and easy to use!

by from 07/23/2012

Been using this product for a few years now. None of my cats seem to have any type of problem after application, except initially when they must feel that "wet spot" on the neck, but that only lasts temporarily. Importantly, no side effects, and I can wait about 5-6 weeks before re-applying.

Effective Treatment for My Three Cats by lala-lou from New Hampshire03/21/2013

When I adopted a stray kitten, he was infested with fleas. I used Frontline on him and my other two cats, but it never really killed all of the fleas. After a few months of treatment, I was still finding a few fleas on them when I ran the flea comb through each of them. (As you know, if you see one or two, there are certainly many more you don't see). Since Frontline didn't seem to take care of them, I tried Advantage II. It appears the fleas are truly gone now. I have combed each of the cats with the flea comb several times since treating them a few weeks ago, and I can't find any fleas or flea droppings. So, I think this is an effective, safe product for my cats. I would recommend it based on the results I've seen.

advantage II for cats works great by sherry from Falling Waters, WV01/28/2013

This works great, wont buy frontline, my vet even told me that it doesnt work. Advantage was recommeded by my vet. My cat is allergic to fleas and they were making her really sick, even though she didnt have them bad. Since I started her on Advantage II for cats, she's doing alot better! The box was pretty dented up when I got it but the medicine was in good shape.

by leslie06/12/2012

We have 2 house kitties and this ensures they remain free of pests that they might otherwise bring indoors.

I don't miss a month by Ragtop10/25/2011

My persian gets this flea treatment at the beginning of each month. She is an 'inside kitty' but I live in a sandy area where fleas can come in on clothing. Knowing the flea cycle, I don't want any hatching going on -- ever. My kitty doesn't either.

best buy for not getting a few Bug,s by shortie from ohio01/13/2013

it,s best to be safe than to end up with a housefull of bugs especially on you loved pets or even your bed. Lets all be safe and protect it all

Great Stuff by Cat Mom from Lake Mary, FL02/23/2013

Overrun with fleas last summer here in Florida, even on a second floor balcony. Tried other products, and the fleas just laughed. This worked great-almost immediately. This is my second time buying it and will come back again.

It arrived quickly. I am unsure if there is a way to stop the boxes from being crushed.

Great product by iLoveMyPets from Ontario10/26/2012

We suspected our dog to have flees, so we got this for our cat as well. After one dose and a couple days, no trace.

flea control by hafepint64 from Florida07/05/2012

Like that it comes in different weight dosages as my cats range from small to extra large. At this point, it appears to be working quite well for my feline family and us!

Using this product for years. by Ms. Lori from pittsburgh, pa03/03/2013

Works great, and love to see those pesky fleas dying instead of chewing up my cats. This product does not kill ticks, which in my case is unnecessary. Will continue to buy.

No problems basically with Adv. II by catangel from pittsburgh, pa.11/17/2011

At first was hesitant in switching from original Advantage. Have not had any problems then...but i do have a 'sensitive cat 9 yrs.old"...even with advantage original though". Seems a tad tummy upset for about 24 hours, then is just fine afterwards.

Works Great by j1975r from California01/10/2012

I have used Frontline Plus on my cat and it just didn't do the job. So, I switched to Advantage ll. I saw great results immediately after the first application, I could literally see dead fleas fall off when I brushed him. I'm staying with Advantage ll Flea Control & Tom is happy I am.

Purchase of Advantage II for Cats by Linda07/10/2012

I could not get over how promptly I received the Advantage II for Cats that I purchased from Entirely Pets. I received my order the very next day after placing my order. I have ordered from Entirely Pets several times before and the Advantage II has worked to keep my cats safe from fleas. The prices are very good and the ability to buy a 6 month and/or 1 year supply is very convenient. I have tried different companies, but I like Entirely Pets the best!

Avantage II for catsVS Frontline for cats by frankie from Morgantown WV07/11/2012

When Frontline stopped working...and I have used it successfully for years) my vet recommended the Advantage...it's amazing!!! and it works great on my cats!

Yes still works well by catlover408/15/2012

Advantage & Advantage II have been effective for both my indoor and outdoor cats thankfully during Florida"s year round fleas! Thank you!

Worth the money by Texas Shopper Donna05/21/2013

Advantage is one of the best flea prevention medicines available. My long hair cat has never had fleas since I used this product. My cat also tolerates it well. Can't beat Entirely Pets prices either!!
