With more than 50 colored wooden blocks (3/4" thick) this toy is sure to outlast other wood toys of similar price - plenty of crunch for your dollar! Parrots are naturally driven to gnaw on wood to keep their beaks trimmed and to keep boredom at bay. This toy provides a fun way for your parrot to do just that. The blocks hang on bird-safe colored poly rope and are sized for large and extra-large parrots, including cockatoos and macaws. A great toy for voracious chewers with no extra gimmicks - perfect for birds that are put off by bells or toys that make noise.
