KONG Catnip Rat Cat Toy is the type of toy your furry friend will love to cuddle. Or attack, depending on its mood. It is made with slippers-shaped fuzzy material that comes with a re-sealable pouch that contains premium KONG catnip. Catnip stimulates your cat's happiness receptors, for more fun. When the catnip scent starts to fade, just replenish it with more fresh catnip. KONG Catnip Rat Cat Toy is machine-washable (with the catnip removed, of course).
