Hope I am not duplicating something already suggested, but pet stores
(and some on-line pet suppliers) often have these great stainless steel
food and water bowls that screw onto the side of the cage - look in the
section for bird/parrot supplies. I acquired a set awhile back, and
they worked great. Might just be a solution for "bowl tippers". I only
like to use glass bowls and bottles now, and I use both bottles and
bowls to be sure mine get enough water.
