Kong Naturals Premium Catnip is made from catnip leaves and flowers grown in North America and harvested at peak flavor, color and fragrance before being field-dried. The premium cut favors leaf and flower over stems and seeds, concentrating the essential oils that trigger a play response in most cats. The dried herb ships in a resealable tin designed to hold in aroma and potency between uses. It can be offered as a standalone treat, sprinkled on scratchers, or used to refill Kong catnip toys and other cat toys. The all-natural ingredients come from renewable resources, and no assembly or preparation is required before use. Once opened, the tin can be resealed and stored in a cool, dry area to help preserve freshness.
