TORONTO -- The Toronto Zoo is encouraging patrons to adopt a reindeer this holiday season—and in exchange they will get a personalized letter from Santa, in addition to the knowledge they are helping a good cause.

For $100, you can get a personalized certificate of adoption, a letter from Santa, a reindeer plush toy, a festive animal fact sheet and a card.

While you can’t bring the reindeer home with you, anyone who adopts the animal will be entered into a draw for a “chance to get up close with a Toronto Zoo reindeer.”

The money collected from the “Adopt-an-Animal” program is used to support the zoo’s scientific research and conservation efforts.

The Toronto Zoo has a number of other “Adopt-an-Animal” packages with different price points. You can choose an animal to adopt from a lengthy list, which includes a number of vulnerable and endangered animals like polar bears and hippopotamuses.
