How does Frontline Plus for Cats and Kittens work?
Frontline Plus for Cats uses S-methoprene, an IGR (insect growth regulator), along with fipronil. These ingredients work in tandem to target fleas in all life stages. Fipronil works by collecting in the hair follicle and skin oils, and it continues to release from the follicles of the hair onto the coat and skin of the cat. This leads to lasting protection against chewing lice, ticks, and fleas.
