Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 90 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

I bought this Frontline plus for my cats and one weighs 22 lbs and my other cat weighs 30 lbs. will this be sufficient to kill all their fleas? Also, I applied the Frontline plus 2 days ago and I am still seeing alot of active adult fleas on their tails and necks. Is this normal? Thank you.
Answer by ChewyJul 16, 2017
You should only need 1 application, even for larger cats. You should apply the entire contents of the applicator in a single spot directly onto the animal's skin, not to their fur. In a study, Frontline Plus began killing fleas 4 hours after application. Another study showed that within 12 hours, Frontline Plus killed 100% of fleas when applied as directed, however to fully eradicate an infestation, treatment of the environment may also be required.

im confused so do i give my cat all of them or just 1 per month
Answer by ChewySep 03, 2017
This treatment should be used once a month and not reapplied for 30 days.

What’s the difference between Frontline Gold & Frontline Plus? I have two adult cats. One is overweight at 25lbs, one is average weight.
Answer by ChewyApr 01, 2020
FRONTLINE Gold is the latest innovation in flea and tick protection from the maker of FRONTLINE Plus. In addition to having fipronil and (S)-methoprene, they now added a powerful third ingredient, pyriproxyfen which helps to kill the next generation of flea eggs and larvae before they can develop into adult fleas. Both products require monthly applications and are safe to use on cats and kittens 8 weeks or older and over 1.5 pounds

Is there an expiration date on these treatment packs?
Answer by ChewyAug 29, 2018
This product does not have an expiration date. As long as you keep it at room temperature and sealed in its original packaging, it will remain ready for use.

Works great for fleas and lice

My house cat mingled with some feral cats that I feed and got lice. I took one of the feral cats to get neutered and the Vet said it was polluted with lice, so they gave it a treatment. My cat had been playing with them so I put this between his shoulder blades and he hasn’t been scratching. No fleas and I can’t see or sense any lice. I am going to use the other two months doses on the feral cats that I can pet and give them some relief.

Been working for years

I have been using this on my cat for years. As long as I do it every month we have no problems with fleas or ticks. There are lots of cats around here, deer and other wildlife so the tick part is important. I also like that they now have a 8 month one, which I bought, which is cost effective and one less thing to deal with through the year. I also love about Chewy that they have a great customer relations team.

Fake product?

I have always relied on frontline when my cats have gotten little “friends” as we call fleas. My indoor cats have not needed flea treatment in years and I had heard good things about Chewy’s prices. This was my first and last frontline purchase from chewy. Product did not work!

disappointed

I put this on all my cats and absolutely did not kill one flea. I have used in the past and worked well, but this time it did nothing. I am so upset because now I have to wait 30 days and spend more money that I don't have.

Great Company

One of the very few really great companies there are. They always do the right thing for the best customer experience. They are quick, efficient and reliable. A+ all the way around.

Still got ticks embedded in face of cat

Used this last year. We have used Bravecto in the past but it’s more expensive. Maybe tics are getting resistant.. found an embedded tic on my cats cheek. I may bite the bullet and go back to Bravecto. .

Jury’s Out

The first application certainly seems to have worked better than the Pet Armour. I am holding my breath and will have to order more rounds but so far, this product is an improvement

Very good protection for cats

We buy Frontline Plus which protects our cat for 6 full months. There has never been any problems with this brand and have not found any fleas on him since we started using it. Very good product

This works for our cat in Maine

Regrettably there are getting to be more and more ticks in Maine. While we never see fleas (no dog or other cats) we have more than our share of wood's edge ticks coming from the grass/woods edges. Once we started using frontline on our last cat the tick issues were reduced. (I wish there was an agent to use on my husband, another tick collector). I like the applicator in the "Plus" version.
