I know several people who have trained their birds to use these. We tried with Stanley when she was very, very young, but she would just sit there like she was waiting to die, and it broke our hearts to see her like that. I've witnessed several birds who just play in them like they are no big deal at all.
Thanks Shivani for the awesome siggy!
