We use only the finest natural Catnip from North America in the refillable Jiggy Toys for Catnip. These toys feature a special clip, allowing new Catnip pouches to be added time and again - lasting through nine lives of your cat. Catnip is a natural, non-addictive herb that encourages play behavior in about 70% of cats, which carry a genetic trait that makes them responsive to Catnip. Includes resealable pouches to maintain maximum freshness and store extra Catnip under necessary conditions until needed.
