We've used this product for several years and it has always worked well for our kitties. We firmly believe this has kept them insect and problem free. This product is made in France, which surprised us. Buy with confidence, and the price here is very competitive !!

Frontline Plus for Cats
June 14, 2016
I have used Frontline and now Frontline Plus for years. This is a product that works and works well on Ticks. We are in a very wooded area and our cats continue to be tick free with this product.

Also, you have to be careful for knock offs but Entirely Pets have always ship the real item and it is a website that I trust.

works well
December 22, 2015
Been ordering this for past few years for my cats. They spend most of their time outdoors in the summer and come inside at their leisure. We have never had a problem with fleas or ticks but we do start treating them in early spring and do it faithfully all summer long. I work at a vet clinic and some people using frontline plus complain it does not work. I think its harder to control fleas if you wait till they have them and your house is infested. I think it works well as long as you start in the spring and use it till there is a hard freeze. For those living where it doesn't freeze, probably best to use it all year. I will buy the product again next spring when it thaws in Ohio. We have 4 cats and I use Frontline Plus on all of them.

Working great so far! I have used for years and has worked well. I have heard people complain that it no longer works well. You need to use it faithfully every month on time and I just don't think people are doing this correclty.

Frontline Plus still remains the best product on the market for dog/cat flea and tick control.

Great product
March 24, 2015
I have used Frontline Plus for over 20 years now and it has always worked well. I have never had a cat that had a bad reaction to this product, unlike some other products on the market for flea and tick control. We live in the woods so there is plenty of opportunity for our kitty to pick up ticks and fleas, but that never seems to happen.

The only review I can give is IT WORKS, that's why I keep buying it for all my cats.

Good stuff for cats
October 7, 2014
This is a good product to use on your cats (inside/outside). I used to alternate between this and the Advantage; so the fleas don't become resistant-it just seems to work better this way for me.

Frontline losing efficacy?
September 23, 2014
I put it on the cat crooked and late. The cat licked it off. Then we got fleas. The vet says she has noticed problems with Frontline possibly losing its effectiveness.

Relief From Fleas!
August 4, 2014
This product for cats seems to work far better than the current experience I am having with my dog with the same product/brand. Not sure why, but my cats don't care about that! They are just happy that they are getting relief from those darn fleas! Would purchase the same product again.

Flea Resistance
July 6, 2014
I have used this product for years but it seems the fleas have developed a resistance to it. I just tried Advantage on my cat and it seems to be working! i hope they don't develop a resistance to this product down the road as well.

slows fleas down
April 1, 2014
I applied the product to the nape of my cats heads. I have 5 cats. and they aren't scratching as bad. I vaccum every few days to cut down on the fleas too. I've, also, washed their beds. I'm hoping the fleas won't be as awful as they were last summer. I'm going to apply more frontline plus this next month & hope for the best.

did the job
November 30, 2013
Used Frontline for the first time. Took 2 treatments for fleas/flea dirt to be controlled. My cat got fleas while being boarded at our vet's kennel. She didn't have fleas for years, as she is indoors. However, this year was supposed to be worse than others. I was pleased with the price and speedy service. Thank you, Entirely Pets. I am a satisfied customer.

Usually good!
November 6, 2013
I have had nothing but good results with this product until this year. it has been a terrible year for fleas so I don't think it is the products fault as it did succeed for the most part, just didn't last as long as usual. Treated the house with knockout and that did the trick.
