Keep your cat protected and your home flea-free with Advantage II for Large Cats, the vet-recommended topical treatment trusted by millions of pet owners. Designed specifically for cats over 9 lbs, Advantage II delivers powerful, long-lasting protection for up to 6 months.

This easy-to-apply formula works through contact — fleas don’t have to bite to die. It starts killing adult fleas within 12 hours and breaks the flea life cycle by eliminating eggs, larvae, and pupae, stopping future infestations before they begin.

With waterproof protection and once-a-month dosing, Advantage II offers a stress-free, mess-free way to keep your cat healthy and itch-free. Whether your cat is an indoor lounger or an outdoor explorer, this treatment provides complete protection with every application.

🌟 Key Benefits

💧 How It Works

Advantage II uses two active ingredients — Imidacloprid and Pyriproxyfen — that work together to kill adult fleas and disrupt the flea life cycle. Applied topically, it spreads across your cat’s skin and coat, providing full-body protection through contact without the need for fleas to bite.

📦 What’s Included

6 × Pre-measured monthly doses (for 6 months of protection)
