My Quaker loves it. It's a safe way that allows the birds that always want to pick the plastic off the strings on you hoodie, to enjoy their own! I would recommend anything from a parakeet to conure/caique/ringneck size.
My cockatoo loves and my caique love. I do take out at night. I worry will get tangled. They are not happy when I take out
My parrot loves these. Way better than destroying the aglets on my shoes! To make them even more fun I tie pony beads on them. She loves untying and pulling the beads off
My Rose-breasted Cockatoo (a medium sized parrot) absolutely loves this toy and spends hours playing with it. He has leaned how to unhook each strand from the main ring pretty quickly so before I give it to him I double-knot each one; he still works them free, but it takes a bit more effort. He will play with every strand until he destroys each aglet part, so I'm glad of the multiple aglets on each strand. Love it!
My bird loves this toy. She plays with my hair and strings all the time. So I wanted to get her something for her cage at night.
