It is not legal to own a pet monkey in many countries, including the United States. In some countries like Canada, it may be legal to own a pet monkey with a specific license, but often requiring an exotic pet permit or certification.
Restrictions may also apply to the type of monkey, size, and species. It is important to research local laws and to ensure that any potential pet meets all of the requirements set forth. Additionally, many animal caregivers and veterinarians suggest not owning a monkey as a pet due to their complex needs and behaviors, difficulty in providing the proper care, and the potential to transmit diseases to humans.
