​​​​Do Zoo Animals Hibernate?

Animals that hibernate in the wild do so because temperatures drop and food supplies become scarce. In the zoo, however, animals live in a controlled environment. They are given a constant supply of food and warm pens or buildings to retreat to when it gets chilly outside. Some animals, including bears, may get sluggish during the coldest months at the zoo, but they will not spend months at a time sleeping as they might do in the wild.
