Our oldest girl (cat), Missy started flipping over her metal food dish when she was hungry.
We had to replace them (OK, we've got several cats) with heavy ceramic dishes except for the one at the other end of the wall, for our most senior male, who has a digestive disorder and needed a special plastic bowl.
It took her about 2 days to figure out she could still flip that plastic bowl over and even though it was 15 feet from hers, when she did it, her bowl would get filled.
