Is It Legal to Keep Finger Monkeys as Pets?

If you want a finger monkey as a pet, you first need to find out if keeping primates, specifically monkeys, as pets is permitted in your state. The private possession of monkeys is expressly forbidden in more than half of all states and the District of Columbia or is permitted only with a specific license, permit, or exemption provided by the state, county, or municipality.

Due to their small size and adorable looks, these little marmosets have become very popular as pets in the United States. Though, they are still wild animals. As was already noted, they eat by boring into tree bark with their long teeth.

Although usually not dangerous, especially to children and other animals, this makes their bite uncomfortable. Aggressive behavior in finger monkeys is well-known, especially in males as they mature. Like other monkeys, they are known to throw their waste when enraged.

These are intelligent creatures, and the first few years of existence profoundly impact them. Because the habits they form now will stick with them for the rest of their lives, you must invest a lot of effort in training them when they are young.

Finger monkeys should ideally be purchased or adopted in pairs. These gregarious creatures cannot maintain their mental health even with plenty of human company.

For their well-being, they must have an interspecies friendship. They can contract human illnesses, including the flu, chicken pox, and HIV. Obtain from the breeder an assurance that your monkeys are in good health. Find out if your neighborhood has a 

veterinarian that specializes in primates before opting to bring one home. These animals can’t be treated effectively by a general practitioner of medicine.


In conclusion, it is impossible to exaggerate how terrible a choice it is for both you and the monkeys to introduce a finger 

monkey into your home. Finger monkeys are wild creatures that should not be kept as pets. Instead, they require other Finger Monkey pals and a full-sized enclosure that resembles their native habitat.

Therefore, finger monkeys don’t make good pets for common pet owners. They might be an excellent addition to a zoo or other businesses, but average pet owners shouldn’t get them.
