Chelsea and Camille are checking out the fur, feathers, and fun at thier local zoo. They love animals and like to make them feel as happy as possible. One way to accomplish this is through enrichment. Zoo enrichment involves giving animals interesting objects, and making their environments seem like home. So when they decided to design an enrichment for tigers and otters, they wondered: how do zoo keepers know what items to give an animal, and what if the animal ignores the enrichment?
