One day, I closed the drain on the tub and ran the water long enough to leave about a half an inch in the tub. Hank was transported to labrador-kitty heaven. He stomped around in the water for a full half hour before rejoining the rest of us. I had go back to the bathroom to check up on him every once in a while, just to make sure he was still ok.
