Query: Rickety Bird Stand

This Bird Stand looks good in the picture, but in reality, it turned over at least three times before our Blue & Gold Macaw became used to how far he could lean. While the original purpose was to allow him to enjoy different areas of the house with us without leaving droppings on the floor, he still does. He climbs on top of the feed cups which allows his rump to hang over the floor below. The feed cups should have been moved further in or the tray made a little larger. Don't know what could have been done to make the stand more stable. It is functional, but not reliable.
