SmartyKat® Catnip Caves™ are irresistible to cats because they combine the allure of a rustling hideaway with stimulating catnip. The surface of the paper is treated inside the bag, so catnip scent is released with every touch – just like a scratch ‘n sniff sticker! Includes two catnip infused bags per package. The paper bags are made with recycled material. Stimulating cat toys attract cats with catnip to engage them to frolic, romp & play.
