Keeping pet monkeys can be a controversial topic as it raises ethical concerns related to the welfare and well-being of the animals. Monkeys have complex social, physical, and psychological needs that can be challenging to meet in a domestic setting. They may suffer from stress, boredom, and health issues when kept as pets. Additionally, the exotic pet trade often involves illegal trafficking and mistreatment of animals. Therefore, many animal welfare organizations and experts advocate against keeping monkeys as pets. It is important to research and consider these ethical considerations before deciding to keep a pet monkey.
