What do you do when the weather is rainy or cold, and your child is stuck inside all day? Dr. Seuss addressed this problem in one of his best-known stories, The Cat in the Hat. The children in this story seemed to be doomed to sit forlornly by the window watching the rain, until the Cat in the Hat comes to entertain. Fortunately you don't need to juggle fish or fly a kite in the kitchen to turn a gray day into a fun day.
