The Kitty Fuzz Bugs are elastic and rustling and produce a fun jingle that stimulates the innate instinct to hunt the cat. Once hooked, the toy can be used as a puzzle or, separated into two parts, it becomes an adorable game with catnip and an inviting ball with an elastic tail. When the fragrance starts to fade, just add a little fresh catnip to still stimulate your cat's fun! The toy is machine washable (after removing catnip).
