Frontline Plus Cat Flea and Tick Treatment, 8 Count, Monthly Protection

FRONTLINE Plus is a topical flea and tick treatment for cats and kittens, with eight monthly applications formulated to protect for 30 days each.

• Eight-count pack — provides a supply of monthly treatments.
• For cats and kittens 8 weeks or older weighing at least 1.5 lb (0.68 kg) — helps you choose for an eligible cat.
• Kills adult fleas, flea eggs, flea larvae, chewing lice and ticks — targets several common external pests.
• Fipronil and (S)-methoprene — target adult fleas and disrupt flea development.
• Waterproof 24 hours after application — protection is designed to remain waterproof after that period.

Fleas can affect cats at different stages of their life cycle, while ticks and chewing lice are additional pests this treatment is made to address. FRONTLINE Plus combines adult-flea control with action against flea eggs and larvae, helping stop existing infestations and prevent new ones. Its single topical application is intended for monthly use, making it suited to ongoing flea and tick protection for eligible cats and kittens.

What pests does FRONTLINE Plus treat?
