Product Overview

Protect your cat with the #1 name in flea and tick protection.* FRONTLINE® Plus flea and tick prevention for cats and kittens is a long-lasting, fast-acting, waterproof flea and tick treatment proven to kill adult fleas, flea eggs, flea larvae, chewing lice and ticks. This flea and tick treatment kills ticks that may transmit Lyme disease. FRONTLINE Plus for Cats has been trusted by pet owners for over 20 years.** This month-long treatment is made for cats and kittens eight weeks or older, weighing 1.5 pounds and greater. Made with two active ingredients, fipronil and (S)-methoprene, this treatment breaks the flea life cycle by killing adult fleas as well as the eggs and larvae and prevents new infestations. One fast-acting topical application protects for a full 30 days.

FRONTLINE® Plus for Cats contains fipronil and the insect growth regulator (IGR) (S)-methoprene. Fipronil kills fleas by affecting their nervous system, making them hyperactive before dying. These dying fleas often rise to the top of the cat’s hair coat as they are dying. The (S)-methoprene prevents all flea stages (eggs, larvae, pupae) from developing.
Cats may experience some temporary irritation at the site of application. If signs persist or become more severe within a few days of application, consult a veterinarian immediately.
Fipronil 9.8%, (S)-Methoprene 11.8%
Contact your closest emergency pet hospital.
For external use only. Do not use on kittens under 8 weeks of age or 1.5 lbs. Individual sensitivities, while rare, may occur after using any pesticide product.
FRONTLINE® Plus for Cats is available in packs containing 3, 6, 8 and 12 treatments.

READ ENTIRE LABEL BEFORE EACH USE. To apply, simply follow these instructions and repeat every 30 days: Use scissors to separate one blister and cut along dotted line. Peel down foil to remove the applicator. Open the applicator by holding upright with foil side toward you and snap applicator tip. Next, part the cat’s hair above the shoulder blades, at the base of the neck. Place the applicator tip just above the skin and squeeze. Apply entire contents of the applicator in a single spot directly onto the cat’s skin. Do not apply on top of the hair coat. Avoid contact with treated area until dry. Do not apply to cats weighing less than 1.5 lbs. or younger than 8 weeks of age. Do not allow your cat to ingest this product. Do not use more than one application per cat per month.


Active Ingredients: fipronil and (S)-methoprene

Works great! Just make sure you apply it on time every month. Also be sure all the liquid is at the bottom of the container otherwise when you snap it open you'll get some of the liquid on your fingers.

I have 6 cats, insiders and inside/outsiders, of varying weights. Frontline is convenient, easy, and effective.

Cheryl D Verified Purchase
May 11, 2016

This is OK for my smaller cats, but not strong enough for my 20 pound cat. I have to used revolution or another one recommended by my vet. I use the automatic refill of this product. Be careful, they accidentally tripled the refill for a 12 month supply (I have 6 cats) and had a bill over $400. I refused one of the refills and they had the nerve to charge me a restocking fee.

Dawn D Verified Purchase

Very effective

Cindy D Verified Purchase
May 9, 2016

I have used Frontline Plus on my cat for years and it remains effective. I prefer using a topical flea treatment over an oral since it is much easier to administer and I like the flesh on my hands and arms. Allivet's service was great!

Lavon B Verified Purchase

In our situation-- ticks from the Maine woods--- using Frontline Plus as indicated on the box has resulted in a significant reduction in the ticks our cat brings into the house. When we are careful to apply correctly we do not see ticks on his neck and have no 'full' ticks drop off.

This is a great quick fix, expecially if your cats are starting with fleas and you are not just in maintenance mode. Within the hour we were able to start combing dead fleas out of our cats coats.

Brian B Verified Purchase
October 28, 2014

I have been using this product for a few years and have always had good results on 3 cats that stay indoors all the time. Alivet also had this for a much better price than 1800 Petmeds, but I found it for $40 cheaper on another site after I had placed my order. Maybe they will price match next time if I call them. Anyhow, it shipped quickly and without issues. Thank you.

Suzanne B Verified Purchase
October 22, 2014

I have used flea collars for many years on my cats but this is so much more effective and a lot less expensive than the vet's office

Anna S Verified Purchase
October 10, 2014

I have been using 800petmeds until I found Allivet and I am very impressed at the savings compared to what I have been paying not to mention free shipping! I plan to use Allivet for all my future pet supply needs.

I tried to save money and purchased Pet Armor at Walmart. In the end I spent more money and had to purchase Frontline plus to get rid of the fleas on my Cats. Thanks Allivet for great prices. Purchased the 12 month supply of Frontline.
