The arctic blast ravaging the U.S. is an invitation for most to stay indoors, but for these animals -- it's playtime. ❄️🐯❄️ http://cbsloc.al/2lSCypl | CBS News

The Chicago Air & Water Show is this weekend! As they do every day, the animals at Lincoln Park Zoo get to pick where to spend their time. Some animals may choose to hang out outside watching the planes go by, while others may choose to head inside to a quieter, indoor space. Want to learn more about how the animals react to the show?

Winter. We're glad that's over! Did you know that many exhibits have heating and cooling elements to provide animals with temperature choices? From heated rocks in Kovler Lion House, to hot springs in Regenstein Macaque Forest, many animals can choose warmer spaces in colder temperatures. Some, as you can see here, still go for the snow! | Lincoln Park Zoo
