One way to get a monkey is to purchase one from a breeder or pet store. Monkeys from breeders can be more expensive and may require a special permit and certificate to keep one as a pet.
Monkeys from pet stores, on the other hand, may be more affordable and readily available. You should, however, take the time to research the source, breeding history, and any necessary licenses or permits beforehand to ensure proper care and legality of owning the animal. In some cases, adopting a monkey from a sanctuary or rescue organization may also be an option.
