Frontline Plus for cats is a topical product that kills fleas within 12 hours of treatment, and ticks within 48. It is also effective for eliminating chewing lice and helps control sarcoptic mange infestations. It works by spreading over the cat's body and collecting in the oil glands of the skin, being dispersed by the natural oils. It is then drawn through the hair over the next 30 days. It can take up to 24 hours for this process to be completed. When fleas are present on your dog, it takes between 23 to 36 hours for them to lay eggs. Research has shown that Frontline will kill the adult fleas before they can lay eggs, in about 12 hours.

Frontline can be used on kittens as young as eight weeks, and is also safe for use on pregnant and lactating cats. It has also been shown to have no reactions to systemic medications. It can even be used on cats who have been treated with other parasite applications, as long as 24 hours have passed.

This product is easy to apply and is highly effective. Unlike some other products, Frontline kills fleas, ticks, and mites that come into contact with your cat's coat. They do not have to bite into the skin. To use, remove the applicator from the packaging, hold it upright and snap the tip away from your face and body. Place the tip on the skin between the shoulder blades, making sure to avoid superficial application the your cat's hair, and then squeeze to empty the entire contents in one area of your cat's skin. Frontline must be used to dry skin, so it is recommended to not bathe your cat for 24 hours before or after application.

As long as Frontline is stored at room temperature in its original packaging, it will not expire.

Frontline Plus kills fleas, their eggs, and larvae for up to three months. If your cat has fleas that might cause dermatitis or if there is a high risk of re-infestation, a monthly application may be necessary to control the parasites. A monthly application is recommended for control of ticks and chewing lice.

Frequency of Use
When used monthly, Frontline Plus for Cats completely breaks the flea life cycle and controls ticks and chewing lice infestations. Research demonstrates that Frontline Plus kills adult fleas, flea eggs, and flea larvae for up to six weeks. Frontline Plus also prevents the development of all flea stages for up to six weeks. Frontline Plus kills ticks for at least one month. A once monthly application is recommended where tick control is needed.  Although Frontline Plus can control fleas up to six weeks, if there is a high risk of reinfestation or if the pet has fleas which may cause flea allergy dermatitis, a once monthly application may be needed.

Frontline Plus remains effective even after bathing, water immersion, or exposure to sunlight. Avoid contact with treated area until dry. So not reapply Frontline Plus for 30 days.

All three of my cats have no problems with this stuff and they sure don't scratch anymore. I'm at war with the fleas and I will win!

It's ok product.

3 stars

My cat has a flea allergy, so I need to use this flea treatment about every 3 weeks. I wish it worked a little bit better and longer. My cat is sometimes irritated in the spot where I apply it. I think it works terrific for keeping away ticks!

Barn Cats without fleas? You bet...

5 stars

We live out in the country and have several cats that live in our barn. We've been giving them frontline for about a year now, and they haven't gotten fleas since. We've also noticed a huge difference in the ticks, which is relieving since we had a couple cats contract lymes disease over the last few years.
