A task force of leading zoologists are mystified by the recent swarms of shoe kittens. These adorable felines have been appearing in footwear around North America, Europe, and Japan. While not a threat to humans, the kittens have caused the loss of thousands of man-hours. Because the kittens cry when taken from their "homes" workers hesitate to remove the cats from their shoes. The cause of this strange upswing in shoe kittens is unknown, but scientists theorize that global warming may be a factor.
