Rated 4.7 out of 5 by 204 reviewers.
Rated 5 out of 5 by They have relief at last!!!! I live in a 3rd floor apt, and some how both my babies ended up with fleas. They were miserable, couldn't relax, losing hair from scratching and would not come near me because I was constantly coming at them with a flea comb. Bought a competitor, and when I applied it, I became terrified as both of them began to froth at the mouth. After 24 hours, I was still finding fleas, and yes, I was vacuuming and applying flea treatment to the carpet and upholstery. After 6 weeks and $100 later, I went back to Advantage. It has been 48 hours and nothing, and I mean nothing. I am still combing them, but no fleas or if I find one it's already gone into the after life. Will NOT be veering from this exceptional product again. Thank you!! October 7, 2016
Rated 5 out of 5 by Needed even for indoor cat The price was less than area stores and was shipped promptly. Would do business again with your company. This product works well on my cat October 17, 2016
Rated 5 out of 5 by My Cats - Jeorgie and Julia Fleas left them the day I put it on and killed all the others in the house. Great product, received in 2 days. October 11, 2016
Rated 5 out of 5 by Awesome stuff!! I have never had a flea problem with my indoor cats until this year. I tried another brand of topical but it didn't work. Within a few hours of applying this stuff my cats finally had relief from their itching!! You can't beat the deals you can find here on Chewy!! October 11, 2016
Rated 5 out of 5 by Safe for 5lb rabbit Vet told me to use only Advantage small cat if I needed flea protection for my house rabbit. It's been a couple weeks now, and he didn't have any issues with it. October 8, 2016
Rated 5 out of 5 by Dependable product Love the larger size package as I have 5 cats. Product works so quickly and is thicker than other flea liquids and doesn't cause any skin reactions in my cats. October 8, 2016
Rated 5 out of 5 by Seems to help with the flea problem I had foster kittens and had a flea problem, used this on my cats and on the floor used a powder then vaccumm. Seems to have worked. October 12, 2016
Rated 5 out of 5 by Finally! I had been fighting fleas on my cat all summer, to no avail. We tried everything on the market and somethings that werent. I finally called the vet to see what they recommended, and it was Advantage. I put it on kitty asap, and finally, FINALLY am deliriously happy to annnounce i have not seen a flea on him in 3 weeks, and he's no longer scratching! Thank you, Advantage! October 5, 2016
