  • can't believe it, work almost immediately!
Size: 2 Pack Style: Large Cat only
My indoor cat had been plagued by fleas since May (as the weather gets hot) thanks to my neighbour's cat coming into our house randomly one day and oh my god, it was bad. poor kitty couldn't stop scratching and us human got flea bites everywhere. At first we tried a flea drop from Sentry Fiproguard, it's as useful as water--it does nothing and every flea I combed out was active and leapt away--it was a useless piece of rubbish. that useless drop was applied 2 weeks ago and we had been pondering for a while, wondering if we should try another drop early on because the flea got really bad. a bathe for the cat (it was like a battlefield) works a bit; combing two hours per day (morning and night, 1 hr each) works better but the fleas just jump back on her; we tried flea medicine and waterless shampoos which has somewhat of an effect but nothing too efficient. In the end we decided to risk it and get a new brand of drop, applied it at the three weeks timeframe. The drop arrived this morning, I immediately applied it and went on my day. An hour later, it's her daily combing section and I noticed majority of the fleas are dead! those that were still alive incapacitated and barely able to move which can easily finish the job by soaking them in water with dish soap. It was quite surprising to me because I had a dog years ago and I used the dog flea drop from this brand, it didn't work so I never tried advantage II again until now--maybe it was an old recipe or something, but the cat version works like wonder. Will definitely use this from now on. ... show more

  • WONDERFUL
Size: 4 Pack Style: Large Cat only
Other than feeding my kitties and "doing kitty boxes" this is the very best thing I have ever done for them. I must mention that catching them and holding them still for the millisecond it takes to apply the stuff is not mentioned in the instructions:) But I did catch them and hold them still and THIS IS MARVELOUS. No more scratching and at least one of my kitties seems to have had a change in personality and has become a lap kitty! So, without vet visit and money spent at the vet, PLEASE get this product, it wont disappoint you wont be sorry and the very next day you will see the results ... show more

  • My cat absolutely hates it, but it works
Size: 2 Pack Style: Large Cat only
Animals are smart, when they aren't dumb. And my cat knows this product by the sound of the packaging and the tube being opened. He looks at me, eyes squinted, blinking in what I feel must be a combination of fear and disgust and will slowly start backing away, running under the bed if he can make it. Ultimately it is for his own good because this product works and without it, my indoor/outdoor kitty ends up neurotically scratching at himself, which seems psychologically worse than being subjected to this medication once a month. Not to mention I am very pleased to not have flees in my house. I've been using this product for two years and it's been reliable, both at keeping the flees away and giving me the opportunity to annoy my cat once a month. ... show more

  • No fleas after first application!
Size: 4 Pack Style: Large Cat only
My adopted feral kitten is now four years old and has never had a flea problem until this hot summer. I bought a flea comb and pulled off 100 fleas the first day, so I first tried Frontline for two months, which reduced the daily morning flea count to under 20, but never got rid of the fleas. So one week ago I switched to Advantage II and have not seen another flea since! ... show more

  • Best Flea Products I've Tried
Size: 6 Pack Style: Large Cat only
I have been using Advantage II for years for my fur babies and it has worked wonders. I live in the countryside so fleas can become really bad, especially during the warmer months of the year (I live in the Northern Hemisphere). I used other flea treatments in the past but nothing works as well as this one. It really does do what it claims to do and I will continue to use this product! Pros: - works great at killing and repelling fleas - have had a flea free home since I started using this product regularly - even works great on outdoor cats - worth the price tag - personally, haven't had issues with toxicity and cats becoming sick from using this medication (however, make sure you are following the directions provided) Cons: - Can be considered pricey, especially if you own more than one cat - Need to have monthly dosages to maintain effectiveness - Can be anxiety inducing to pet owners who prefer not to put chemicals on their pet - Has a chemically smell and takes roughly 24 hours to completely dry ... show more

  • It's #1 rated for a reason
Size: 1 Pack Style: Large Cat only
I got a cat recently and was told by the vet that my cat needed a flea treatment every mouth. He recommended this and it's rated #1 here on Amazon as well. It was easy to apply and no mess. Also like the fact that you use it once and throw it away. Will order a box with more viles next time.

  • It’s a product that actually works.
Size: 6 Pack Style: Large Cat only
We have a cat that is feral. We had to coax her for a couple of years to get her to come into our house. And still to this day she does not want to be picked up, although she has become socialized in the last 3 years. She still loves spending time outdoors do she’s in need of a flea Med in order to avoid becoming infested. This product, unlike most others sold over the counter, actually keeps the flea problem under control. We buy the box of six applications because that pretty much covers the flea season where we live in the Mid West. And, it costs less than half the money the Vet charges, so it’s a good deal, as well as a good product. ... show more

  • A little disappointed
Size: 2 Pack Style: Large Cat only
I have used this product before and it worked great. This time I found it not to last quite as long as it was claimed to last. Have they changed the formula? I wonder.
