Advantage Orange for Cats 0–4kg is a single-dose spot-on flea treatment for kittens and small cats. It kills fleas on contact without needing them to bite, making it a fast-acting option for young cats and those with flea allergy sensitivity.

The imidacloprid-based formula kills 98–100% of fleas within 20 minutes of application. Re-infesting fleas stop biting within 3–5 minutes and are killed within an hour. The waterproof formula also kills flea larvae in the cat's surroundings, reducing the risk of re-infestation. Safe for use on kittens from birth and on pregnant and lactating cats.

Advantage's contact-kill mechanism provides relief before fleas can bite, which is why it's often the first recommendation for cats showing signs of flea allergy dermatitis. The single-dose pack suits owners testing the product or topping up an existing supply.
