Medium Spinning Blocks will make a fun and colorful addition to the birdcage. The different textures of the leather and wood make this toy the perfect outlet for chewing. The toy also spins and spins, engaging birds for hours. This toy is recommended for large birds such as African greys and cockatoos. We also added bells on the ends for extra sound stimulation. The wood pieces are dyed using natural food dyes, so feathered friends can play it safe while having fun!
