The Rawhide Chew Balls are ideal foot toys for just about any beaked buddy! The 3401 includes four ready to play with woven balls made with strips of all natural raw hide. Each ball is made with wide strips of natural rawhide woven and twisted into a sphere. On the ball there are many nooks and gaps, letting your pet easily interact and play with them. They can be picked up, carried around and thrown all over! The color of the balls has a nice muted soft look as the rawhide is uncolored. You can even hang them on other toys, parts of the cage or whatever your imagination comes up with. The pack weighs about 6 ounces. Each ball measures approximately 2 inches in diameter but this will vary from item to item. The 3401 is 100% bird safe.
