I purchased three of these bowls. I placed one up high, secured by the holder included. Our little girl parrotlet, Gracie, has a smaller cage than our other parrotlet, so the holder would not work on her cage. I still like the bowl, because it is heavy and can't be turned over. The bowls are also attractive. I probably should have gotten smaller for them, but it is nice for the little guys to have some variety. I wonder if the holder on a smaller bowl would have worked on Gravie's cage with its horizontal bars?
