We couldn't leave our big guys out when we created three sizes of this very unique bird toy. Made with cockatoos in mind, but honestly, any bird will enjoy it. My birds use it as a nice place to snuggle and sleep. It mounts on the side of your cage with two stainless steel bolts and wing nuts. Just place it over your birds favorite perch area and watch them preen and snuggle. Lots of bird safe superior cotton rope used on this toy! It has a neat concave shape to it, to kind of wrap around your bird a little bit. Very durable, and long lasting toy!
