Protect Your Cat from Fleas with Cheristin™ for cats

Fleas can be a maddening problem for cats and cat owners. Your pet may be exposed to these blood-sucking parasites almost anywhere: in your backyard, walking around the neighborhood — even in your own home. Each female flea can produce 40 to 50 eggs a day, up to 2,000 in their lifetime3. So even a few fleas can turn into a major infestation in a matter of days.

Cheristin for cats kills fleas fast, lasts a full month and is easy to use — all in a single flea control product.

While lethal for fleas, Cheristin is gentle for cats and kittens eight weeks of age and older. And it's available only from your veterinarian — your best source of healthcare advice for your cat.
