The last one, a female, passed away in early 2015. A troop of cotton top tamarins now resides in the enclosure.
That kind of sucks, I wish that the zoo would get more new African Monkey Species aside from Mandrills and Colobus Monkeys, which are the most common African monkey species at zoos. Also, I heard that the Milwaukee County Zoo exhibits domestic cats, do you have some pictures?
Milwaukee County still has a solid primate collection, in my opinion. They don't have much room for new species at the moment.
