Advantage Cat with Imidacloprid as active ingredient works preventively and curatively against fleas. The product stops fleas biting in 3 to 5 minutes and kills adult fleas within the hour, before they can lay eggs. The fleas present on your cat are all killed within 24 to 48 hours of administration. A single treatment with Advantage Cat protects your cat against fleas for 4 weeks. Treatment with these pipettes can also be used as part of a strategy for treating flea allergy/dermatitis.

Hercontamination due to the emergence of new fleas in the environment may persist for six weeks or longer after the start of treatment. More than one treatment may therefore be necessary depending on the amount of fleas in the environment.
