KONG Naturals Premium Catnip is high-quality North American catnip that your cat will go crazy for. To ensure the catnip is paramount, it is harvested at the height of it's flavor, color, and fragrance. Naturals Premium Catnip contains minimal stems and seeds, and instead provides more of the essential oils that cats love. Though it can be used on its own, your cat is sure to enjoy it even more if it is in a KONG refillable catnip toy. As an added bonus, all ingredients used to make Naturals come from natural and renewable resources, and as such the product is ecologically responsible.
