Advantage II Large Cat Flea Treatment, 1 Count, 30-Day Protection

Advantage II Large Cat is a monthly topical flea treatment and prevention for cats and kittens over 9 lb (4.1 kg), designed to kill adult fleas, flea larvae and flea eggs.

• Kills adult fleas, larvae and eggs through contact — targets three stages of the flea life cycle.
• Starts killing fleas within 12 hours and works for 30 days — supports monthly flea control.
• Made for cats at least 8 weeks old and over 9 lb (4.1 kg) — helps you choose the right size treatment.
• Fragrance-free and waterproof 24 hours after application — fits a low-fragrance routine with a defined water-resistance window.
• Vet-recommended topical treatment with no prescription needed — applies without pills or a flea collar.

Fleas can make cats uncomfortable and may be associated with health risks, including tapeworm transmission, flea allergy dermatitis and flea bite anemia. Advantage II Large Cat is made for monthly flea treatment and prevention on indoor or outdoor cats. Its contact action means fleas do not have to bite the cat to be killed.

Which cats can use Advantage II Large Cat?

Advantage II Large Cat is for cats and kittens that are at least 8 weeks old and weigh over 9 lb (4.1 kg). It is suitable for indoor and outdoor cats, so the intended setting does not change the stated age and weight requirements. The treatment is supplied as a 1-count product for the large-cat size range.

• Check both requirements before use: age of at least 8 weeks and weight over 9 lb (4.1 kg).
• Designed for cats and kittens, not for cats below the stated age or weight threshold.

How is the topical treatment applied?

Apply the spot-on treatment to the skin at the back of the cat’s neck, at the base of the skull. Place the tube tip on the skin and squeeze out the entire contents directly onto the skin. The application takes seconds and avoids giving a pill or fitting a flea collar.

Advantage II Large Cat works through contact: fleas can be killed without biting the cat first. It begins killing fleas within 12 hours of application and continues working for 30 days, helping control an existing infestation and prevent further infestations during that period. Follow the product label’s application directions and review its potential side-effect information.

• Apply the complete contents of the tube directly to the skin.
• Use the base of the skull as the application location.
• The product is waterproof after 24 hours of application.

What flea protection does one treatment provide?

Advantage II Large Cat kills adult fleas, flea larvae and flea eggs, addressing multiple stages rather than adult fleas alone. By acting on these stages, the monthly treatment is designed to break the flea life cycle, control existing flea infestations and help prevent new ones. Its 30-day period of activity supports a regular monthly treatment schedule.

Flea control matters because fleas can cause discomfort and may contribute to tapeworm transmission, flea allergy dermatitis and flea bite anemia. Advantage II Large Cat is a vet-recommended, leading brand in cat flea protection, and it is available without a prescription.

• Targets adult fleas, flea larvae and flea eggs.
• Made for monthly use on eligible indoor or outdoor cats.

Advantage II Large Cat suits cat owners looking for a quick, spot-on monthly routine for a cat or kitten that meets the age and weight requirements. It is especially suited to households that prefer topical application over pills or a flea collar; the product is fragrance-free and becomes waterproof after 24 hours. Its fit is defined by the cat’s age, weight and the stated monthly treatment interval.
