USDA Organic. Certified Organic by OneCert. Your pet deserves the best. Organically grown for feline euphoria. Not all catnip is created equal. PetGuard's growing practices ensure that absolutely no toxic synthetic fertilizers, herbicides, or pesticides are used in our fields. PetGuard's catnip leaves and flowers are harvested at the peak of potency and then air dried naturally to capture and maintain a lasting aromatic scent that your kitty will find irresistible. Our cats sniff the catnip, lick it, rub their head in it, roll around on their backs and all the while gratefully purring feline euphoria! Made in the USA.
