Fleas can cause discomfort for cats and may also transmit tapeworms or contribute to flea allergy dermatitis and flea bite anemia. Advantage II Large Cat is made for monthly flea control on indoor and outdoor cats, with a spot-on format for owners who want to apply treatment directly to the skin rather than use a flea collar or an oral pill. Its contact action means fleas do not have to bite before the treatment kills them.

Which flea stages does Advantage II Large Cat target?

Advantage II Large Cat targets adult fleas, flea larvae, and flea eggs. Addressing these three stages is designed to interrupt the flea life cycle, helping control an existing infestation and prevent further flea infestations during the treatment period. The product is intended for monthly use, so it provides a recurring approach to flea protection rather than a one-time application.

• Three-stage flea action covers adults, larvae, and eggs.
• Monthly treatment is designed to control existing infestations and help prevent new ones.

How quickly does it work, and do fleas need to bite?

Advantage II Large Cat starts killing fleas within 12 hours of application, and kills reinfesting fleas within 2 hours. Its contact action kills fleas without requiring them to bite your cat first. This makes the treatment relevant for owners seeking flea control that acts on the cat rather than relying on a flea needing to feed.

• Fleas already on the cat: killed within 12 hours.
• Reinfesting fleas: killed within 2 hours.
• Contact action: a flea bite is not required for the treatment to work.

How do you apply the topical treatment?

Apply the treatment to the skin at the back of your cat’s neck, at the base of the skull. Place the tube tip against the skin and squeeze out the entire contents directly onto the skin. This spot-on method is designed to take seconds and avoids giving a pill or fitting a flea collar. Follow the product label for application directions and information about potential side effects.

• Application site: skin at the back of the neck, near the base of the skull.
• Application method: empty the tube contents directly onto the skin.
• Waterproof timing: the treatment is waterproof after 24 hours.
