Colorado Parks and Wildlife said it is legal to own a reindeer in Colorado.
Reindeer and caribou are the same animal (Rangifer tarandus) and are a member of the deer family. In Europe, they are called reindeer. In North America, the animals are called caribou if they are wild and reindeer if they are domesticated, the United States Food and Drug Administration said.
