Night monkeys, also called owl monkeys because of the size of their eyes and the shape of their faces, are the only nocturnal monkeys in the world. The trade of night monkeys has been regulated by the Convention on International Trade in Endangered Species, but if it’s legal to buy or adopt one from a certified breeder in your area, you can own an owl monkey for $5,900. Once you have your new pet, you need to invest in an indoor or outdoor cage that’s furnished to closely look like its natural habitat in the wild. It also needs a healthy diet of fruits, leaves, flowers, insects, and supplements. Lastly, you’ll need to set aside funds for visits to the vet and a supply of diapers if you’re planning to keep your night monkey indoors.
