Your cat may drool, run around and act crazy when exposed to catnip. Only about half of all cats will get this excited to this natural herb. Thus you are in for fun time if you are lucky enough to have a cat who reacts to it. Try again in a few months if your cat doesn’t react at first. Catnip is safe and cause no long-term effects or damage to your cat. Your cat doesn’t have to eat the catnip since she will be affected after sniffing it. Insert some catnip into your cat’s toys or blankets. The effects of catnip will last for about twenty minutes. Take it away after that time. If you wait about an hour, you can give the catnip back to your cat for more fun. Keep catnip fresh by sealing it in a plastic bag when not in use.
