This year's feast included sweet potato pie topped with popcorn, cranberry sauce, steamed vegetables, and a turkey made of monkey biscuits, honey and water.
The ring-tailed lemurs were also treated to a Thanksgiving parade complete with floats that highlighted the zoo's Roosevelt Fountain, Chicago Wolves skating rink and even the Chicago skyline. Ramses the lemur couldn't resist stealing a snack of dried cranberries that donned each float.
Those attending Chicago's Thanksgiving Day Parade on November 22 can also see a float from the Brookfield Zoo.
And if you're looking for something to do before your own Thanksgiving feast, admission to the zoo is free on Thursday.
