I have had Juni perform this trick for Vermontcat when she came over a couple of years ago.

You can put a glass of anything, on the table or floor, and call her over and she will walk up to it and knock it over! She started doing that at the dinning room table, much to my dismay.

I put a glass of water in the basin, at all times, and that seems to have stopped her for some reason. She doesn't knock that one over....and has finally stopped doing the same to my glasses next to the bed, at night.

I will have to tell you, Juni ruined many a meal, by jumping up on the table and swatting the glasses....filled with tea or milk or water....didn't matter.

By the way, Juni was far from a kitten when she began the trick.

I hesitate to test her skills right now, for fear it will remind her how much fun it was...... for her, not me.

Try the glass filled with water in a sink and see what happens.
