The Advantage II Large Cat Vet-Recommended Flea Treatment & Prevention (4-Month Supply, Cats Over 9 lbs.) has been a game-changer for my indoor-outdoor cat. This topical solution, backed by veterinarians, is super easy to apply—just a quick squeeze at the base of the skull, no pills required. The fragrance-free formula kills fleas, larvae, and eggs on contact within 12 hours, preventing bites and breaking the flea life cycle for a full 30 days per dose. My cat’s scratching stopped almost immediately, and I’ve noticed no fleas since starting the treatment. The 4-month supply is convenient and cost-effective, with no prescription needed, and the waterproof formula holds up after 24 hours, perfect for my cat who loves exploring. The active ingredients, imidacloprid and pyriproxyfen, work effectively without needing fleas to bite, reducing risks like tapeworm or dermatitis. Application is straightforward, though I ensure my cat doesn’t lick the spot initially to avoid mild salivation. While some users report rare skin irritation, my cat had no issues, but I’d suggest monitoring after the first use and consulting a vet for sensitive pets. For anyone with a cat over 9 lbs. needing reliable flea control, this is a solid, vet-trusted choice that delivers peace of mind and a happy, itch-free pet! Consult a veterinarian before use.

Our kitty enjoys a flea free lifestyle after we apply this medication. We have been using this for several years and it seems to work better than other brands we have tried in the past. Within 24 hours, there is no more scratching. Now she has time to enjoy the more important things in life.

Used this for my cat and worked great! Got rid of the fleas and mites in under a week. The scratching stopped. I was ver nervous buying from amazon but would definitely recommend.

It definitely works as my cat has never had flees. (Knock on wood) And it is easy to apply. The only reason I gave it one less star is because my cat HATES it. When I apply the liquid to the back of my cat’s neck/head, she blinks her eyes a lot like the chemical is bothering her eyes (like it’s in the air around her eyes). She will then proceed to panic and will be darting around the house and hiding, darting, hiding in a cycle, trying to get away from it for awhile after the application of it.

I have been using this for years on my girls and it is very effective. Plus I got it on sale which was even more awesome.

Been using this for year on both cats. I have a big cat (25 lbs) and a l regular size (12lbs). One season I forgot to get this and within a month they started to get fleas. Put this product on and haven't had a issue since. Easy to apply and easy application .

Well, I'm unsatisfied overall. I have been using this flea and tick medicine for 4 months now and I have been pulling ticks off my cat. And just to be super specific i just reapplied meds to him a week ago and pulled two ticks off him today. Now, I have to say it's only around his eyes or crawling on his fur but I constantly have to check him. Unfortunately, for the price I was hoping for better results. Moving forward with another bread.
