Catnip can cause your cat to become very excited as she drools, runs around and acts crazy. It is a natural herb that only about half of all cats will react to. You are in for a treat if your cat reacts to it. Your cat’s sensitivity may develop later so if she doesn’t react, try six months later. Catnip is a safe, fun herb with no long-term effects. Your cats will react catnip after sniffing it. Thus your cat doesn’t need to eat it. You can put catnip into toys or blankets that your cat plays with. She will go crazy over catnip for about twenty minutes. Take away the catnip after that time. In about an hour or so you can give it back to her for more fun. If you store your catnip in a sealed plastic bag, it will stay fresh when not in use. For more information, contact your veterinarian Green Bay WI.
