You can hold a monkey in California if you obtain a permit from the California Department of Fish and Wildlife. According to the Department’s website, a permit is required to own or keep any wild animal in captivity. Prospective monkey owners may contact their local Department office for more information.
Furthermore, holding a monkey in California may be subject to local ordinances, and applicants must meet certain criteria to obtain the permit. Before considering the addition of a monkey to any California home, prospective owners should research all applicable state and local laws.
