It used to work better. Im switching to Bravecto now that its had a couple years on the Market. It probably works well on some cats so Im giving it a 4. I have 15 cats.

I have used Frontline Plus for both dogs and my cats with great success for several years. It works! I have not been able to get out to shop and the quick free delivery is greatly appreciated!

The Frontline seems to work best for out cat. We live in Florida and use it all year. The cat spends about 6-8 hours outside every day and flea treatment is very important.

useless on my dogs and cats, cant get rid of the fleas, even in the middle of winter. there arent any in my house but they are on all my cats and dogs and frontline each month does nothing. did they make this weaker in order to make more money?

My cat is indoor/ outdoor and she came in every day for a week straight with a tick on her. I purchased this and within two days it began to work - we haven’t seen any ticks for a whole week.

i like the fact it kills fleas, eggs and larva. Yes I did take bug samples before and they were disgusting. 3 weeks later nothing has hatched almost all are dried up and dead. Nice to find a product for 13 animals for under $350.00.

I used Frontline for over 10 years and figured I would save $30 by getting Pet Action which did not work. After wasting $ on Pet Action which did not work I bought Frontline. Frontline I never should have left ye! Though the ingrediants are the same it is the carrying (inert ingrediants that make Front line work. Thats what my vet told me and I believe her.

This past fall we moved into a house that was unfortunately infested with fleas. First time we have ever had to deal with fleas so this was all new to us. When I first shopped for flea killing products I bought a cheap brand as I also bought carpet powder, house spray, and flea bombs. (Thought I had all bases covered!) After the first month of none of that taking care of the problem, I bought this brand and treated both cats. I was initially disappointed that the fleas didn't instantly die off as I had thought by their claim of die off in hours. I called Frontline and they explained that the fleas can live on the pet for up to 18 hours and the reason I was still seeing fleas was because of staggered hatching. UGH!!! I continued to vacuum daily and by the second month of treatment of this brand all the fleas have disappeared.

didn't kill the fleas on the kittens I bought it because it was supposed to be good you can see the fleas crawling on the kittens

Use this every month and my indoor/outdoor cat has never brought in fleas or ticks from the woods outside. A much needed item in our cat care regime.
