The brightly colored JW Pet Activitoy Hypno Wheel bird toy is great for the stimulation and exercise required for your pet bird's well-being. Tiny knobs are perfectly sized to allow small beaks to spin the wheel. The bell rings and chimes as the wheel turns and the silver balls inside will keep your pet bird entertained for hours. Just don't stare at the Hypno Wheel too long or your feathered friend will put you in a trance and there's no telling how many more toys he will convince you to buy! Great for Parakeets, Cockatiels and other similar sized pet birds.
