I have a grown male cat that has started this horrible habit of spilling most of his water either by dragging the bowl around with his paws, or splashing it around. No matter how many times I yell at him, he will not stop. Now I don't know whether he had enough water or if he has spilled his bowl. Any suggestions on how to stop this? I tried changing the bowl from a automatic feeder to a regular bowl. I don't want him to be thirsty, but I also don't want my rug ruined cause of the water!!!
