Advantage Purple for Large Cats over 4kg is a 4-pack of monthly spot-on flea treatment dosed for the larger cat weight tier. It kills fleas on contact without biting, making it a fast-acting option for adult cats in households where flea control is the priority.

Each pipette delivers imidacloprid, which kills fleas on contact within minutes and stops re-infesting fleas from biting within 3–5 minutes. The formula also targets flea larvae in the cat's environment, breaking the re-infestation cycle. Water-resistant, and safe for use on pregnant and lactating cats.

Advantage handles flea control without bundling in tick or worm ingredients, which suits cat owners already running separate parasite products. The purple pack is the large-cat tier, ensuring proper dosing for cats over 4kg.
