Playtime is more invigorating than ever with SmartyKat Silvervine Cat Attractant Catnip! This stimulating blend of silvervine and catnip is purr-fect for cats who need a little extra excitement. Silvervine, a wild member of the kiwifruit family, is foraged in the mountains of Japan and China. This natural, non-addictive herb has a strong effect on cats—even those who don't respond to catnip! Great for use as a training tool, you can sprinkle this herbal blend on items you would like them to scratch or play with. Most cats will respond with a burst of energy followed by a calm, mellow period. Plus, it comes in a resealable pouch or canister to help keep things fresh!
