KONG Holiday Refillables characters will keep your cat wrestling, swatting, and pouncing all day! They're soft and cuddly on the outside, but inside, these holly jolly friends have a refillable pouch that holds fresh catnip securely in place. Our Holiday Refillables characters come with a generous amount of KONG Premium North American Catnip in a reclosable vial. When the catnip scent starts to fade or your cat loses their holiday spirit, replenish with fresh catnip. To help keep it fresh, store your catnip vial in the freezer. Or to refresh the toy itself, you can hand-wash and air-dry it after removing the catnip. Holiday Refillables make an ideal gift for curious cats, allowing them to join in on the seasonal fun. 1: Pull the inner "hidden" flaps to open. 2: Insert/replace catnip. 3: Tuck flaps back in and press firmly to seal.
