Yeah that surprised me as well. A number of different types of monkies in a zoo I visited were previously used as pets and given to the zoo after being rescued or owner wasn't able to take care of them anymore.
Evidently taking care of them is a little more difficult because they don't have any medical history when they come in, so the keepers are kind of flying blind at first while learning the animals medical needs.
