How to Care for a Marmoset Monkey: Essential Tips for Exotic Pet Owners

How to Care for a Marmoset Monkey: Essential Tips for Exotic Pet Owners. In this video, we'll talk about how to care for a marmoset monkey. First, set up the marmoset’s new home. 1. Get a cage that's 6 feet tall, 6 feet wide, and 3 feet deep. The width and height are important because marmosets like jumping around. 2. Connect this cage to an outdoor enclosure to expose your marmoset to direct sunlight. Marmoset monkeys need vitamin D3 to develop a stronger bone structure. 3. If you cannot provide an outdoor enclosure, sprinkle vitamin D3 powder in the marmoset’s food several times a week. 4. Use branches, grass, trees, swings, and platforms in the outdoor enclosure to stimulate activity.
