Fast-acting, effective flea control for your cat

Two’s company—and fleas a crowd! Cheristin for cats is a once-a-month topical solution for the prevention and treatment of flea infestations.

One dose, one size, one solution

Cheristin® for cats is hard on fleas:

  • Starts working in just 30 minutes and kills 100% of fleas in 12 hours in a controlled laboratory study1
  • Provides ¬ ≥99% flea control for a full month2
  • One low-volume dose for all cats
  • For cats and kittens 8 weeks of age or older and 1.8 lbs of body weight or greater


The active ingredient in Cheristin is spinetoram, registered in 2007 for use on a variety of fruits and tree nuts. The introduction of spinetoram for use in agriculture resulted in the receipt of a Presidential Green Chemistry Award in 2008. The award was presented to Dow AgroSciences LLC. In the context of agricultural use, spinetoram has a lower environmental impact than do many current insecticides because both its use rate and toxicity to non-target species is low.3

  • Severe flea infestations can cause anemia, especially in kittens or debilitated adult cats.
  • Ingested fleas may transmit tapeworm infection.

For the optimal flea control results

  • Treat all animals in the household with an approved flea control product
  • Vacuum where your cat sits and sleeps and launder bedding
