SmartyKat® Catnip Caves™ are irresistible to cats because they combine the allure of a rustling hideaway with stimulating catnip. We’ve treated the surface of the paper 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. Made in the USA
