Advantage Purple for Cats over 4kg is a monthly spot-on flea treatment dosed for the larger cat weight tier. It kills fleas on contact without needing them to bite, providing fast-acting flea control for adult cats where parasite management is the priority.

Each pipette delivers imidacloprid, which kills fleas on contact 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 once dry, and safe for use on pregnant and lactating cats. The purple pack is specifically calibrated for cats over 4kg.

Advantage handles flea control without bundling in tick or worm ingredients, which suits owners already running separate parasite products. The colour-coded weight tiers make dosing straightforward in multi-cat households on different pack sizes.
