Frontline Plus for cats is a topical 'spot-on' application for the treatment and prevention of flea infestation, ticks and biting lice on cats and kittens. Frontline Plus has a rapid onset of action and kills re-infestations with newly acquired adult fleas for at least one month on cats. Frontline Plus also prevents the development of flea eggs, larvae and pupae produced by any adult fleas acquired for up to 6 weeks after treatment. Frontline Plus can be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD) in cats. It can be used on kittens from 8 weeks of age and is safe to use on breeding, pregnant or lactating animals. Frontline Plus is waterfast from 48 hours after application.
