Doesn't work at all. I put it on my cat and it doesn't affect the fleas or ticks at all. Terrible product.

10 days ago I purchased 2x6pks of frontline plus for my cats. I wish I had checked here first because they don't work. My cats still have fleas and are suffering and my bank account is also suffering after having to buy more drops from another company. I would never recommend Frontline to anyone.

I wish I had read reviews before I purchased Frontline Plus for cats. I bought a pack of 6 with extra three as a bonus from Budget Pet Products and what a waste of money! My two cats are inside cats and have NEVER had fleas before so I was shocked to find them scratching. I bought Frontline Plus and applied it right away but after a week they still have fleas and they are still very much alive. Judging by reviews of this product on several sites I'm not the only one who has had a problem with this totally useless product Frontline Plus. My vet recommends Advantage so I'll be buying that next time from our Vet.

2 applications, 3 weeks apart and the fleas are still as lively as ever! Never again! will stick to Advantage in future.

bought this product and its useless, complained to company, sent another packet, fleas kept multiplying, had to go out and purchase advantage, fleas gone in a matter of hours. company said no one else had complained, so I came on reviews and it seems it not just me as company had implied. NEVER buy frontline plus again, you have lost a customer frontline and you dont seem to care either

I got the advice of my vet to up this on my two cats well 3 months later and $80 down the drain they still have Fleas very disappointed in my vets chose and the product

I always used Advantage on my cats and was never bothered by fleas. When the store was out of Advantage, I thought I'd try Frontline Plus for Cats. My poor cats were infested with fleas. I'd never seen so many on one animal and they also got in the house! I had one h--- of a problem! When I called my vet for advice on how to get rid of them, he told me to get rid of the Frontline and get them back on Advantage, giving them one dose, then another dose in two weeks if the fleas are not gone. He also told me how to get ahead of the fleas in the house. I followed his instructions and we are flea-free once again. Do not buy FRONTLINE. My vet said it's the worst. I won't take a chance on any other product but Advantage.

Wish I'd read the reviews on this product before purchasing. Purchased it from a large reputable pet store. It is complete rubbish, might as well have sprinkled water on our cat. Did absolutely nothing. Followed all the instructions closely and after 3 months of application our cat still has fleas and our house is now infested!! Did not see ANY reduction in fleas, not even for one day, over this time period. A complete waste of money. PLEASE DO NOT BUY THIS PRODUCT!!!

We usually use Advantage, but the vet was out of it. Six weeks later, big cat has fleas again, although very few. We believe that Small cat was poisoned by the treatment and did not eat for a week and has not eaten properly since. Her behaviour changed also. Our beautiful sixteen year old cat is skin and bones and will probably not survive. The vet has found a lump in her stomach, which she says was triggered by the treatment.

Frontline is the worst product ever! My cat was terribly sick, to the point where we had to take him to the vet! Surprisingly we were informed that #frontline is terrible for all animals, as it contains poison! $1800.00 later, our cat is over the hump. I wouldn't, and I hope no one else purchases any of their products.

I have been using this product for 3 months - advised to use it every two weeks in the warmer weather, and its a complete failure regarding fleas. It simply doesn't work and I am hearing it over and over now. I even heard from a friend in Brazil that it doesn't work! This is a very expensive product and companies need to be accountable for what they produce and claim.

Fleas have developed a resistance to this product. Have used it for a few years now but it no longer works. I consulted with the local vet who advised he no longer stocks this product due to flea resistance. He advised it is still effective against ticks though and is one of the few tick products for cats. Manufacturer should re-formulate this product or stop selling it as a flea treatment, reduce the price and market as a tick treatment only. Don't waste your money.

Same for cat as for dog, except it made my cat's neck really itchy when I tried to give her affection (once the Frontline had dried). Wish I could give it a zero. It's supposed to last for one month but it doesn't even work on day one. This stuff is a pathetic excuse for flea treatment and so damn expensive. Very annoyed. Not getting Frontline anymore.

I've been using Frontline and Frontline for many years but in the past 2 years didn't work on my cats.
I am totally disappointed that the producer is not hearing us, and totally frustrated that they keep raising the price like nothing happening with their product.
All over Sydney the people are returning the Frontline to the shops, asking for money back.
I will never buy again this product.

Please do not waste your money on Frontline Plus for Cats. It not only doesn't work but also they do not guarantee it. Purchase advantage II instead it works.

I used this product twice in an effort to rid fleas from my cat to no avail, now I have as many fleas on me as my cat! Like the majority of other reviews, I would not recommend this product.

Don't buy this product, as stated below it works for a day or two then there back on the cats. Would have given minus stars if possible.. Buy Advantage plus, dearer but worth it in the long run.

I bought Frontline plus for my cat. She had picked up fleas on the screen porch!!! I have used this product two months now and still comb fleas out daily! I also see eggs and fleas hatching on her. When I called for the "Satisfaction Guarantee" while on hold, I heard for the guarantee to be effective you had to buy it at your vet! Where you can spend another 75.00-100.00 for them to tell you the cat has fleas! I don't need a diploma hanging on my wall to tell me she has flea and then have them charge me more for Frontline! The product is useless and expensive! The package does not say you have to buy it from your vet to have satisfaction guarantee!!
I'm tired of vets and companies like this taking advantage of the pet owner.
