My amazing moving water dish is often tripped over by me when it mysteriously is transported from the edge of the kitchen into the center. Doesn't matter that it's a heavy dish holding a container that's SUPPOSED to last a few days....Most of the water is somehow osmosised into the air (or hardwood floor..) rendering the bowl and attached container bone dry only a few hours after being filled. Don't know why this corresponds with Shy's wet underside and feet when she leaps onto the bed....Mysterious....
