Advantage II Flea Control Large Cat Unless you take preventive measures using a high-quality anti-flea product there is no real way of preventing flea infestations in your cat. Cats often get fleas from other cats or while they are playing out in the backyard. Fleas can not only cause skin irritation, but they are also carriers of dangerous pathogens. Advantage II by Bayer is a great product that can be applied to eliminate existing flea population and as a preventive. This purple pack Advantage is specially formulated for large cats weighing over 9lbs. The product launches a 3-pronged attack by simultaneously destroying adult fleas, larvae, and eggs.

The product’s advanced formulation is completely waterproof, which means your cat is free to roam and be in contact with water. The pack contains two tubes which provide two-month protection against fleas.

    Key Benefits:
  • Veterinarian-recommended treatment kills all life stages of fleas on kittens and cats 8 weeks or older and weighing over 9 pounds.
  • Begins working within 12 hours to kill fleas on contact with no painful biting required.
  • Kills eggs, larvae and adult fleas to break the life-cycle and help prevent re-infestation
  • Waterproof formula continues working for up to four weeks, even after bathing.
  • Convenient, monthly topical application contains imidacloprid and pyriproxyfen


Active Ingredients by Weight
Imidacloprid 9.10%
Pyriproxyfen 0.46%
Other Ingredients 90.44%
Total 100.00%

Useful Information

    How To Open:
  • Be sure tube is at the bottom of pouch.
  • Using scissors, cut the pouch across the top and remove tube.
    How to Apply
  • Remove one applicator tube from the package. See "HOW TO OPEN" section
  • Hold application to be in an upright position facing away from you and your pet's face and eyes. Pull the cap off tube.
  • Turn the cap around and place other ends of cap back on tube.
  • Twist cap to break the seal, then remove the cap from tube.
  • Part the hair on the neck at the base of the skull until the skin is visible. Place the tip of the tube on the skin and squeeze the tube to expel the entire contents directly on the skin. Do not get this product in your cat’s eyes, or allow your cat to ingest this product. The product is bitter tasting and salivation may occur for a short time if the cat licks the product immediately after treatment. Treatment at the base of the skull will minimize the opportunity for the cat to lick the product. Do not allow the product to run off.
  • Discard empty tube as described in Storage and Disposal.
  • Under normal conditions this product is effective for a month. However, in cases of severe flea infestation, retreatment may be necessary earlier than four (4) weeks. Do not retreat more often than once every fourteen (14) days for kittens or once every seven (7) days for small and large cats. After flea control is attained, return to a monthly retreatment schedule.
  • Use only on cats or kittens 8 weeks and older. Do not apply to cats or kittens weighing less than 9 lbs. Do not use on other animals.
  • Do not apply more than one (1) tube per treatment, even for larger cats.
  • Do not have contact or allow children to have contact with treated area until completely dry.

great product
I had purchased another flea topical product and used it for 3 months, but did not see any improvement. I then decided to try this Advantage II and was amazed and how quickly it worked. I now believe the first product was somehow defective. I will continue to purchase this product, from Entirely Pets, because of how well it worked and this company's customer service. I consistently receive my orders in less than 4 days. This is critical, especially when dealing with a flea problem. Entirely Pets is Great!!

Not as efficient as :Frontline
My old cat was back to inching and scratching within a week of treatment. I have had better results using the more expensive Frontline product.

Advantage II for large cats
By the time I received the Advantage II flea meds for cats, my two cats were infested. Was not sure if this medication would work. Boy, was I wrong. Withing 24 hours, I could not find any fleas on my cats, plus, there were no side-effects. Everything I have tried always made one of my cats sick. She was lethargic for two day and I was always concerned. Not anymore!

Advantage for Large Cats
This works great in our warm tropical weather. I've use it on my 3 cats and will continue to use it and order it from ENTIRELY PETS who have given me excellent service for many years. The main reason I chose this co was that their shipping costs to Hawaii was reasonable; all others were over-the-top! Now that the others have made their shipping costs reasonable "too little too late". I will remain loyal to this company because they were honest from the beginning. I get my order very quickly too.
Thank you ENTIRELY PETS people!!!

Great product
My cat has sensitive skin and would lose hair at site of application with other products. I haven't had that problem since switching to Advantage II and it works great. The price is a good value as well.

Easy to apply
Products is easy to apply. My cats do not mind the application because the amount is small. The location applied is between shoulders so cats can not reach.

Excellent Product
My big Siamese-Burmese is indoor cat however caught fleas but she's allergy to Frontier and to Activyl prescribed by her Vet. After application she developed black bruise on the area applied with the medications (both Frontier and Activyl) and then later developed bald spot on that same area that get in contact of the previous 2 products. It is only with Advantage that she didn't have allergy reaction and it all got rid of the fleas completely. Now she's back in bed with me!

Saved my life!
My 4 cats do not go outside however they love to sit by the sliding glass door when it is open and I am sure that the fleas come in. They are so bothered when they have fleas! Within 12 hours after Advantage is put on them they begin to rest peacefully and I see dead fleas. I brush them constantly and they feel like a million bucks!!!

WOW! Finally a really good flea product!!
I have ten cats and fleas have been a problem until I found Advantage II. I had tried a number of different products with little or no success in controlling the fleas - that is until I tried Advantage II. Advantage II works great! The cats no longer have ANY fleas
and therefore no more skin irritation. I will recommend Advantage II to every pet owner that I know. .

It Only Works for A While
Advantage used to be sufficient to kill fleas on my cats, but repeated use has rendered it less effective over time.

Disappointed :-(
I followed the instructions to a tee and my cats still have fleas; not sure whether to blame myself or the product but my cats stay indoors and the product did not work for any of them.
