Great interactive toy for your curious pet birds. Brings hours of enjoyment and even the pickiest birds LOVE the colorful toy. Wiffle balls run through leather chords and attach to a chain in the middle. Hanging from the bottom of the chain and hidden among the wiffle balls is a bell. Our birds went nuts going through the colorful delights to find that hidden gem! The toy attaches to your cage with a pearl link closure. Great for small and medium birds such as Green Cheek Conures, Sun Conures, Quakers, Caiques, Queen of Bavaria (Golden Conure), Smaller African Greys and Cockatoos.
