The soft and snuggly Kong Duckie plush catnip toys has a reclosable pouch to hold fresh catnip securely in place. The toys include a generous amount of KONG's premium North American catnip in a reclosable vial. When the catnip scent starts to fade, simply add more fresh catnip for another round of fun! Catnip can be stored in the freezer to help keep it fresh. The toy is machine washable with the catnip removed.
