Can CBD Kill a Cat?
No, pure CBD is not known to be lethal to cats and there is no established fatal dose; the serious danger is THC, which is toxic to cats, not CBD itself. High CBD doses may cause drooling or stomach upset, but the real risks are THC, xylitol, and essential oils in human products, which is why cat CBD must be THC-free and pet-made.
This is a fair worry, but pure CBD has a wide safety margin in cats and no known lethal dose. Where cats get seriously ill is with THC, which is toxic to them and causes signs like stumbling, dilated pupils, drooling, and lethargy, sometimes needing veterinary care. Cats are small and sensitive, so even a little THC affects them strongly, which is exactly why any product for a cat must be completely THC-free. What people fear as CBD poisoning is almost always THC or another ingredient rather than the CBD.
Human products carry the real hazards. Xylitol and certain essential oils and flavorings can be dangerous for cats, whose livers handle some compounds poorly, so never give a cat a human CBD product and use a pet-formulated, THC-free one with a certificate of analysis. If your cat ingests THC or shows signs like severe wobbliness, dilated pupils, or unresponsiveness, contact your veterinarian or an animal poison control line right away.
