Rated 4.7 out of 5 by 250 reviewers.
Rated 5 out of 5 by The Best I recently got a cat from the SPCA. Unfortunately, she brought along a couple of friends of the flea variety. I had some Frontline that I had used one time on my previous cat (RIP) when I realized she wouldn't let me try to comb her - and it did NOTHING! I went online and did a search to see if there was something comparable to the K9 Advantix that I use on my dog - and thought I would give this a try! The cat flea treatment is as good and the flea and tick treatment I use for my dog. Now - if they could only find a way for me to apply it without getting her mad at me! December 29, 2016
Rated 5 out of 5 by Worked amazing! My indoor cat somehow got fles. I tried every diy thing. no luck. Tried Adams blue worthless! Bought this and we are now flea free!! January 10, 2017
Rated 5 out of 5 by Pricey but worth it! I ordered this 4 days ago and it was delivered to my door this morning. I applied it to my 2 flea infested cats, left the house for a few hours, and when I came back there were no living fleas in sight. I saw a couple of dead fleas on their chins. They aren't scratching as much. The cats seem to be quite happy with their new found relief! More playful and social than usual. I am very satisfied with Advantage II. My cats had no negative reactions to this product. Just try to apply it very high on your cat's neck to avoid them licking it off. Also, if you have multiple cats, separate them so they don't groom each other. By the end of the day, the medicine will be completely absorbed and dry. There are no weird smells. I will also be applying the dog version of this brand to my pit mix tomorrow (after she gets cleaned and her natural oils come back). I'll write a review on that as well. October 30, 2016
Rated 5 out of 5 by Product Works Well I purchased this product as a step up from the kitten variety, as my cats are now getting much bigger. Seems to work the way it is supposed to and I will continue using this product. January 7, 2017
Rated 4 out of 5 by This product works very well and it's easy to use This product is very easy to use and it is very effective. The cats do not mind it's application. January 6, 2017
Rated 5 out of 5 by Works great Used a store brand product previously and that seemed to bother her almost immediately after application and it worked great the first time but didn't do anything but drive her crazy the second time. Used Advantage II and it didn't bother her one bit when I applied it and all the fleas were gone the next day. January 1, 2017
Rated 5 out of 5 by I have used this product for years it is wonderful Our family has 3 dogs and a cat. My little babies mean the world to me and they only get the best. I feel that this is the best product for my babies to prevent fleas. January 5, 2017
