Cheristin is a topical flea treatment for cats and available without a prescription. It provides fast-acting relief from flea infestations, killing fleas in 30 minutes with 98% – 100% of fleas killed in 12 hours, working faster than Frontline Plus and Advantage II. Unlike other flea treatments, Cheristin's low-volume dose is approved to use on kittens and cats over 1.8 lbs. and 8 weeks of age, making it a great addition to multi-cat households who don't want to keep track of multiple products. Cheristin is an easy-to-apply topical flea treatment with a non-greasy, quick-drying formula. Hold applicator tube in an upright position and open applicator tube by twisting the nozzle tip. Part the hair on your cat's neck at the base of the head until the skin is visible. Place the open tip of the tube directly above their skin and squeeze 2-4 times onto the skin. Discard the empty tube and in 30 minutes, fleas will begin dying. Cheristin is a trademark of Elanco or its affiliates.
