Advantage XD Large Cat Flea Prevention & Treatment For Cats over 9lbs. | 4-Topical Doses, 2-Months of Protection Per Dose

Kills fleas almost instantly, the dead fleas just fall off. I will buy this brand from now on, it's just that good! Great price!

Works for now, but fleas are evolving

Fantastic product. Helped kitty tremendously. 😺 very convenient.

Applied this to my 3 cats about 4 days ago and it appears to have worked! No signs of live fleas on the short haired ones anymore and no side effects to speak of which is great because I was worried about skin irritation from trying a new product.It was easy enough to apply once I realized you didn't have to take the cap completely off and I'm pleased that you only have to apply it once every two months as I am forgetful.My only complaint is that it has been four days and my long haired cat (pictured) still has funky gunky residue on their fur. I applied it at the base of their skull per the instructions and the goo seems to have settled into their hair and is now collecting dust. This is less worrisome for me as my cats don't groom each other but if you have bonded cats this may be a problem as you don't want them ingesting the product. Cleaning it off of my cats neck will also be an issue because washing a cat is a perilous task.

used this product for a long time

This really works. I haven't had any fleas in 2yrs

I've used this product several times but am beginning to wonder if it's worse for my cats or better, now.When I used it the first two times, I could not detect a smell but this third time, it really stinks and there is wayyyyyyyyyyyyy to much liquid for small cats! I think someone has changed the formula, I feel, for the bad to my animals, I would guess, they're adding more fillers, less treatment and I don't like that at all, it's crooked and scary because my cats are like family to us, we have 9!!!!Plus the price has gone way up, and since I have 9, I'll probably be finding something which I feel is safer for my animals!Not good when a "good" product gets messed with and isn't good for our animals and/or doesn't work like it once did, not good business, but this is just my opinion.

I used it on two cats and in both cases, it didn't fully take care of the fleas. Although they were mostly reduced- I'd say 75% less fleas, I'll be going to go back to Advantage II. Although not fully effective, the XD still takes longer to wear off, so the cats have had to wait an extra month before it's safe to give them any other treatment. That bums us all out.
