Living World Wacky Pyramid is a multi-purpose, interactive toy for birds. The unique, 3-sided wooden pyramid structure with 16 colorful acrylic/plastic mobile stars, flowers and circles encourage birds to spin, chew and play. The multi-tiered pyramid promotes play and beneficial activity, such as exercise, climbing and spinning. Wacky Pyramid also doubles as a perch and provides a practical way to weigh birds. You can hang the pyramid in the cage or use it as a tabletop toy. It has a hanging length of approximately 40cm (16 inches) and can be attached safely to the cage with a bird-safe, nickel-plated C-clamp and hangs from a leather strap. Made with food-grade colorants only, Wacky Pyramid is completely safe for bird to chew. The small size is made specifically for small hookbills.
