Frontline Plus for Cats - 6 Pack

Frontline Plus for Cats is a monthly, topical “spot-on” treatment designed to protect cats and kittens (from 8 weeks old) against fleas, ticks, and biting lice. The 6-pack provides enough doses for six months of protection (assuming monthly application). This treatment not only kills adult fleas and ticks, but also interrupts the flea life cycle — preventing eggs, larvae, and pupae from maturing and causing reinfestation.

This 6-pack expires July 2026.

Key Benefits

• Fast-acting & effective — kills 98–100% of adult fleas within 24 hours of application. 

• Lifecycle disruption — contains an insect growth regulator that prevents flea eggs, larvae and pupae from developing; breaks the flea breeding cycle to stop reinfestation. 

• Long-lasting protection — one application protects for up to 30 days (and through repeated monthly use, helps maintain continuous protection). 

• Water-resistant — remains effective even if your cat gets wet after 24 hours post-application. 

• Safe & versatile — suitable for kittens from 8 weeks old, and can be used on breeding, pregnant or lactating cats (as directed). 

• Convenient to use — easy “spot-on” application: part the fur at the base of the cat’s neck (or between the shoulder blades) and apply the pipette directly to the skin. One dose per month. 

Ingredients / Active Components

• Fipronil — this is the main adulticide: it disrupts the nervous system of adult fleas and ticks, leading to paralysis and death. 

• (S)-methoprene — an insect growth regulator (IGR) that stops flea eggs and larvae from developing into pupae and adult fleas — effectively breaking the flea life cycle. 

Typical composition in the cat-specific formula is approximately 100 g/L fipronil and 120 g/L (S)-methoprene (in a 0.5 mL pipette).
