The primary ingredient of Cheristin for Cats, a topical flea treatment, is spinetoram, which targets the neurological systems of fleas to cause quick paralysis and death. For cats and kittens 8 weeks or older and weighing at least 1.8 lbs, it provides long-lasting protection, begins to act within 30 minutes, and eliminates up to 100% of fleas within 12 hours. The solution is perfect for households with multiple cats because it is simple to use and made specifically for external applications on cats.
