Customer Ratings & Reviews

Rated 4.7 out of 5 by 144 reviewers.
Rated 5 out of 5 by Great product for keeping fleas off cat. I have been using this product for years. I wouldn't use anything else. Once I used a supermarket bought flea collar and almost killed my cat --it was neurotoxic to the cat. Thank goodness the vet saved him and recommended this product. I found it at chewy for a great price and my cat is happy and flea less!!! Thank-goodness. December 20, 2013
Rated 5 out of 5 by Fantastic Results We had tried the Frontline Plus and less than a week later very, very poor results. The next month we tried the Advantage as suggested by our Vet and within 24 hrs we saw huge results. Now with 7 rescue cats this was imperative to get good results. Never had fleas before until 2 of our cats brought them home from a local new groomer which spread with weeks to all the cats. Chewy is now programmed into my phone and I love the prices and fast shipping. A+ to the reps who take care of my needs. I have told friends and family and now they are Chewy customers too.

Rated 5 out of 5 by Excellent, safe, total flea treatment I consider Advantage II the best flea treatment on the market because it is safe for my cats and kills fleas and eggs. Within days, cats' coats are better looking, scratching is abated and the fleas are gone. Permanently. September 30, 2013
