Sicilian Donkey looking for the oregano

Workers at Canada's Edmonton Zoo with a culinary bent and a passion for spicing up the lives of  animals have incorporated spices and scents into the daily vittles. Because scent plays such a major role in the wild, animal care team leader Wade Krasnow says it's important to recreate it in captivity in a way that keeps animals active and engaged.

Staff sprinkle different spices in the animals' habitats: on the ground, on branches, under rocks, and it's appreciated. Lucy the elephant won't take her medicine unless she detects the aroma of cinnamon; lemurs like banana or coconut; Arctic wolves dig cloves. In fact, wolf sisters Shilah and Kayok immediately drop to the ground and roll in the cloves.
