Animals at the zoo get treats every day -- not just on Christmas. Zookeepers give them anything from balls and bungees to puzzles and pinatas, perfume scents, specialty treats and more.
Lincoln Park Zoo actually has a wish list on its website, where you can give gifts to zoo critters.
The zoo still features its ZooLights presented by ComEd and Charter One through January 2, 2011. They're on every night from 5 to 9 p.m.
