  • Safe for senior cat
Size: 2-Pack Style: Large Cat only
I love it ! It worked just took a couple hours to fully stop my cats from itching. I had tried capstar and capaction and the fleas kept coming back and I don’t even let my cats outside so I tried this and it worked got rid of fleas and stopped my cats from itching. Im very happy I was nervous at first bc my cat is a senior cat and sensitive but it all worked out. Only downside is that it’s topical so even if you put it on their back between their shoulders it leaks sideways, so I put a shirt on them overnight till it dried up in a way. My younger cat licked it and started salivating like crazy that’s why I suggest you put on a shirt on them if you apply it because I’m sure it’s not safe for them to ingest I had to rinse his mouth out it was very scary but he is fine! Make sure you always stay around your pet to watch for any reactions and to make sure they don’t lick it! Great quality and came a couple hours after I placed the order. ... show more

  • Absolutely worth the price
Size: 4-Pack Style: Large Cat only
I’ve used this product multiple times for my cats, and it works perfectly every single time. It’s highly effective, easy to use, and has never caused any issues for my pets. I’ve been consistently impressed with the results, and it has become my go-to solution for keeping my cats flea-free. I’m incredibly satisfied and would recommend it to anyone looking for a reliable flea treatment. ... show more

  • It Works
Size: 6-Pack Style: Large Cat only
Best Flea protection by far! Since using Advantage II, the fleas are gone! Works fast in just 24 hours our cat was scratching a whole lot less and a few days later almost all the fleas were gone! Our family has been using this for a couple months now and our cat is flea free and happy again. I would highly recommend Advantage II. Thanks so much for making a great flea protection that truly works! ... show more

  • Works, but .....
Size: 6-Pack Style: Large Cat only
Doesn't seem to be completely effective, although nothing nowadays is. Fleas appear to have developed a resistance to everything available including spray pesticides.

  • Works!
Size: 2-Pack Style: Large Cat only
Fleas are hard to eliminate. They breed quickly and often. Some are resistant to current insecticides. This product works well on our cats and it is easy to apply. You will need to apply this monthly to maintain consistent pest control.

  • Kills fleas and flea eggs
Size: 2-Pack Style: Large Cat only
I've tried other flea medicine that hasn't worked and have had to wait weeks before using a better treatment. This is the heavy duty stuff that will annihilate a flea infestation. My cats hate the smell of it, but they don't seem to get any skin irritation. Great product, worth the money.

  • Still works with some alternative options
Size: 1-Pack Style: Large Cat only
Used this for all my cats I've ever owned and loved. Still use it for my new strictly indoor kitty babies: 7 year old tuxedo boy, 4 year old dilute tortie girl, and 8 month old Russian blue baby boy...works like it always had except one issue I am seeing this year in particular in northeast United States....I have started to apply doses of 1/4 of a tube once every 2 weeks to actually rid them all of the fleas from coming back which is the first year in over a decade I've had to do this w these types of meds (I used a different brand before until it no longer did anything)...fleas are becoming stronger to survive the meds I think....but if you do the whole every 2 weeks for 2 months (after giving them whole tube/make sure you use the one strictly FOR THEIR AGE AND WEIGHT) of a 1/4 or less of a tube on each cat you'll be flea free for months....but I stand by this product 100 percent cuz it's the only one I've ever used for a decade now that doesn't attempt to harm or kill my cats like some other products similar... ... show more

  • Works But Not For Long
Size: 6-Pack Style: Large Cat only
The first time I used this product on my two large cats, it was apparent that it worked quickly. One of our cats had chewed off his fur on his belly and legs before treatment and his hair began to grow back within a few days of treatment. Unfortunately, both cats began scratching again after 10 days. Since this product allows reapplication every week for up to 4 times, I simply reapplied and the product lasted 15 days before the treatment stopped working. I have now treated them for a third time and will wait to see how long the treatment is effective. I also vacuum almost daily, spray with Vet's Best Home Spray, and check the cats daily with a flea comb. I found live fleas on both cats at the end of the 10 day and the 15 day treatments. Mine are inside only cats and the only pets. Since I used the Elanco Advantage II, I have ordered the Bayer Advantage II to see if that makes a difference in the length of effectiveness. I found application to be very easy and my cats have had no adverse reaction to the medication. I just wish it worked longer than it does. Treatments were done exactly as directed. ... show more
