Modeled after a big slice of a tree, this calcium toy provides lots of healthy chewing time. Toy is 12 long with a perch that is 1/2 inch in diameter and 1 1/2 inches long. Suitable for Senegal size birds up to Macaws. The smaller birds can sit on the perch and nibble and the larger birds can enjoy the calcium from their own perches or the side of their cages. Assorted colors.
