Marmoset Monkey

Tiny primates with enormous personalities

Marmosets are among the smallest primates in the world, but their care requirements are anything but small. They are highly intelligent, social, and emotionally complex animals that require significant time, space, and expertise to thrive.

01

Housing

Marmosets need a very large, tall enclosure — at minimum 6×6×6 feet — with branches, ropes, and platforms for climbing. They are arboreal and spend most of their time off the ground. The enclosure must be escape-proof and easy to clean. Outdoor access in warm climates is beneficial.

02

Diet & Nutrition

A marmoset diet includes commercial primate biscuits, fresh fruits, vegetables, insects, and tree gum supplements. Vitamin D3 supplementation is critical — marmosets are prone to metabolic bone disease without adequate UV exposure or supplementation. Never feed processed human food.

03

Social Needs

Marmosets are colony animals and suffer psychologically when kept alone. They should be housed in pairs or small groups. They form deep bonds with their owners but require daily, multi-hour interaction. Isolation leads to stress, self-harm, and illness.

04

Health & Veterinary Care

Find a primate-experienced exotic vet before acquiring a marmoset. They require regular fecal exams, dental checks, and metabolic panels. Common issues include Herpesvirus saimiri (fatal to marmosets), wasting marmoset syndrome, and dental disease. Strict hygiene protocols are essential.

05

Legal Considerations

Primate ownership is heavily regulated and prohibited in many US states. A USDA exhibitor or breeder license may be required. Exotic Kingdom provides full documentation, health certificates, and guidance on legal requirements in your state.
