As the Cat and Co. mingle with reindeer, musk oxen, polar bears, caribou, and all sorts of penguins, they discover how the animals stay warm in freezing temeratures, why it's colder at the South Pole than at the North Pole, that one pole is located on land and the other isn't, and how scientists are studying climate change to keep both poles icy cold. Perfect for fans of the hit PBS kids TV show The Cat in the Hat Knows a Lot About That, this is a great choice for curling up with on a winter's day!
