Customer Reviews

Rated 4.7 out of 5 by 161 reviewers.
Rated 5 out of 5 by It works this product works, almost immediate results. but be aware of this, I have multiple cats, and their reaction varies, have used this product before and the reaction spectrum is always there. some cats, never know that anything was done except no scratching. some cats "get down" for a short while, (day), and one of mine was sluggish for two days. So NEVER get a large size for a medium cat thinking that a more is better, it is not, But bottom line is the treatment actually lasts longer than advertised, so I would wait until its obvious that they need treating again. On the lighter side, some cats know what is happening after you do it the first time, Got one tom that shoots the gap as soon as he ralizes that I am going to get the back of his neck wet with the treatment, and after its run jump anything to get away from that wet feeling. His brother, no big deal. June 17, 2016

Rated 1 out of 5 by Not very happy I have 3 cats; 1 of which likes to sneak out the front door frequently and pick up visitors to share with his siblings. I tried this advantage and it didn't kill anything. 3 weeks later and he and the others still have fleas. As a single mom on a budget, I hate having to waste money.... I'm disappointed. Now on to try the next product. July 13, 2016
Rated 4 out of 5 by This product works After trying many other brands, this product has eventually killed every fleas on my very hairy cat. July 11, 2016
Rated 5 out of 5 by Converted Customer We recently tried advantage II for my indoor/outdoor cat because we just couldn't get a handle on his fleas. Despite a topical product and Capstar, his fleas kept coming back. I switched to advantage, and within 2 days, all of his fleas were gone. We applied the advantage, gave him a Capstar, and he has been flea-free ever since and had no side effects whatsoever (he lost fur at the application site with other products). I won't buy anything else now, we are very happy with the result. July 7, 2016
Rated 5 out of 5 by Very effective I use this on all my indoor/outdoor cats and we have no fleas! Living in Florida that says alot. July 15, 2016
Rated 5 out of 5 by Really Works! I had been using a product with ingredients like Frontline and it was not working. Talked to my vet and in the Gulf Coast area they have found that it no longer works on fleas. Switched to Advantage and no more fleas. Cats are happy and so am I. July 11, 2016
