Advantage Purple is a monthly spot-on flea treatment for large cats weighing over 4kg, including kittens of that weight. It's manufactured by Elanco and targets fleas at multiple life cycle stages.

Applied to the skin at the back of the neck, the formula spreads through the coat's oily layer and remains active for a month. It kills fleas on contact — they don't need to bite to be affected — and addresses both adult fleas and larvae in the immediate environment. The formula is water-resistant once dry. Each pack contains four pre-measured pipettes.

Advantage Purple is a well-established choice for cat owners managing flea infestations or maintaining year-round prevention. The once-monthly application schedule and no-bite-required action make it practical for cats that are difficult to handle.
