Tigers, bears and chimps like pumpkins. More importantly though, they are a good addition to the animals' diet.

Here are some photos and video from the pumpkin enrichment that several of the animals, including lions, tigers, polar bears, brown bears, and the gorillas, were given as part of the behavioral enrichment program in honour of the upcoming holiday - Halloween.

All photos are taken at the Brookfield Zoo on October 28.

Halloween (also spelled Hallowe'en) is an annual holiday celebrated on October 31. It has roots in the Celtic festival of Samhain and the Christian holy day of All Saints. It is largely a secular celebration but some have expressed strong feelings about perceived religious overtones.
