The Racket bird toy will be sure to cause quite a racket in the birdcage. The bells dangling on strings of colorful plastic beads will be sure to entice feathered friends to tug and pull on this noise making machine. The bells are made from nickel plated alloy, and the beads are made from BPA-free plastic. We recommend this toy for medium-sized birds. The quick link allows the toy to attach to virtually any birdcage.
