If your cat is not responding to catnip you can try a silvervine plant or a shrub called Tartarian honeysuckle. There are other alternatives, like the Cat Twig Silvervine Stick toy. Some products have both catnip and silvervine, like Petlinks HyperNip and Catnip Blend, Petlinks HyperNip Hoppers cat toys.
Other plants that you can try are rosemary and peppermint. They also have a stimulating effect on cats. If you want your cat to use a scratch post, spray catnip on it and chances are the cat will use the scratch post. The cats that like catnip will increase play behavior and activity.
Things that cats like to do with their catnip are: sniff it, roll all over and rub themselves on it, chew and lick it and rub the cheeks all over it.
