A finger monkey, technically known as a pygmy marmoset, is a type of small monkey native to the rain forests of South America. The best place to find a finger monkey is through a reputable breeder. Breeding centers or private breeders can be found through the internet or in local publications depending on the jurisdiction of where you live.
It is important to make sure the breeder has a good reputation of health of the animals they sell. A finger monkey is a fragile animal that requires proper care and attention, therefore choosing a healthy and reputable breeder is key.
