Frontline Cats 6pk – Effective Flea Control for Pets
FRONTLINE PLUS contains two active ingredients to break the flea life cycle at every stage. One ingredient, fipronil, kills adult fleas on your pet, while the other, (S)-methoprene, kills flea eggs and prevents larval and pupal development. (S)-methoprene stops fertile flea eggs from being laid throughout the month, reducing reinfestation and preventing flea spread in the home environment.
Fleas can breed year-round, so monthly treatment is essential even during winter. When applied correctly, FRONTLINE PLUS remains active on the pet’s skin for one month. Treat all cats and dogs every month to maintain consistent protection.

My cat has been flea-free since using FRONTLINE PLUS monthly. The treatment is easy to apply and the stickers help me keep track of when I last treated her. No more flea bites or dirt on her fur.

Great product. My cat stayed flea-free even during colder months. The two-ingredient formula works well and I notice fewer flea eggs in the house now.
