Perfect foraging toy for those birds that are too smart for their own good and this Foraging Carousel Bolt-on Bird Toy happens to be one of the most challenging! The carousel has four compartments and each has a door on it that can be opened, however each door opens in a different way so that is four different puzzles in one bird toy. This toy is more challenging and recommended for birds who have already mastered the basic foraging toys. Dimensions 6" x 6"
