Monkeys are inquisitive and intelligent animals with large brains that give them a wide range of cognitive abilities. They often use objects as tools – for example, some capuchin monkeys will spontaneously use stones to crack nuts. They can also use sticks to help them reach and break open the shells of some vertebrates and insects. Unlike the great apes, however, they do not seem to be particularly adept at learning from their peers – although individual monkeys may learn new behaviours for themselves.
For most monkey species, fruit is the primary food source. They move around their habitats to find the different varieties of fruits available, depending on season. Some, like baboons and marmosets, have cheek pouches that they fill with fruit to consume later, while others, such as langurs, have chambered stomachs to help them digest leaves. Some species will even eat meat, such as young antelope or birds like guinea fowl, though this is a rare occurrence for most of them.
If monkeys are used in research, they will usually be humanely killed as part of the experiment. If they are no longer needed, some may be rehomed into sanctuaries. However, it is important to ensure that rehomed monkeys are going to legitimate sanctuaries and are receiving the best possible quality of life there. Rehomed monkeys should not be sold to private owners, as it is not in their best interests.
Before buying a monkey, it is essential to check with your state wildlife authorities to find out what regulations apply in your area (if any). You will need to meet minimum age requirements, pass a lengthy application process and pay high fees for each animal you acquire, as well as undergo regular wellness checks. The cost of looking after a monkey is expensive, but it is the only way to guarantee that your animal will receive all the love and care it needs in its lifetime.
