Details: Cheristin protects your cat from fleas with a novel molecule called spinetoram. Spinetoram is derived from spinosad, a fermentation product found occurring naturally in bacteria in the soil. This fermentation product has proven to be a powerful insect control molecule and has been widely used to treat insect infestations in agriculture, livestock, dogs, cats and people. As Cheristin’s active ingredient, spinetoram kills fleas before they lay eggs. This novel molecule is toxic to the flea’s nervous system, but has low toxicity to mammals and other non-target organisms. Spinetoram is proven to be potent, to begin working fast and to have a long duration of activity.
