Perfect for medium to large birds. Constructed of solid aluminum and stainless steel, this toy is built to last a lifetime. Parrots love its bright colors and the clanky sounds it makes as they take it apart by unscrewing the wing-nuts. Put a treat inside and let them go at it! Mounts securely to the side or top of their cage. The wing nuts won’t fall off, so you’re never digging on the bottom of the cage to find them! Chemical and dishwasher safe.
