Advantage II Vet-Recommended Flea Prevention for Large Cats 9 lbs+, 2-Monthly Treatments

This product did not work for our cats. One week after applying to our cats they all still had as many fleas as they had when we put it on them. We went for a special subscription treatment from our vet and the fleas started to fall off on the first day.

Didn't work. Saw two fleas side-by-side on my cat's tail this morning. Saw a few crawl across her face last night too. This stuff does nothing. It's frustrating because I went and researched the heck out of topical flea treatments before buying this. I'm convinced topicals just aren't effective. Flea collars don't work either. It's gotta be oral medication, which means a vet visit and a hefty vet bill. It's like the system is set up for middle class people to struggle just to provide decent care for their pets. I can buy a gun as easily as walking into a store, but I need to see a vet before I can buy flea, tick, worm treatments that are effective. It's weird since they say it's to protect innocent animal lives. I can't help but question, “So you trust me with a gun but not with flea and tick preventative?”

Burned skin on half of my 6 cats, leaving a bald patch on each one. What makes it even worse? Two weeks later they are scratching like something is crawling on their skin :( I don't understand why this is allowed to be stocked on any store shelves at all. What ever happened to 'do no harm'? My poor babies

Does not work on my outdoor cat at all. I applied it, and two days later, I found fleas on my cat. I re-applied the following week, and two days later, again, I found more fleas. I did this 3 weeks in a row, and still finding fleas. Three applications in one month and still fleas, so I would not recommend this for outdoor cats.

I have a mostly outdoor cat. So I understand he is exposed to fleas all the time. I spray the yard and do my best to keep fleas and ants at bay. But I find I have to use this product twice a month for best results. It's very expensive to have to do that but it's the best I can do. Maybe for an indoor cat it does a better job. But not so much for an outdoor cat. Thanks , Marsha
