Quite possible the most annoying bird toy on the planet, simply because it stands up to its name! My cockatoo spent hours trying to get into the case to break the bell, all while thrashing and screaming his head off and having a blast. For bell crazy birds this is the toy for you, but you may want to buy some ear plugs!
Indestructibell it is indeed. Our DYHA Birdo has thrashed it and chewed at it and gets totally frustrated. Actually, the sound of that bell is a good thing. Birdo is challenged and engaged. Oh, how she wants that metal clapper. :)
