Squid, our dear departed Aby male, used to push things off counters and the like. His worst was a full six-cup tea kettle sitting (cold) on the stove. It crashed to the floor dumping all the water and destroying the kettle. He routinely pushed pans off the stove, storage containers off the top of the refrigerator, coins off the dresser... literally anything that would or could fall. Mango has one of Squid's traits which is pulling a glass over to look in it and then dumping the contents. Mango dumped a glass of Coke the other night and I thought I was doing such a good job of guarding it!
