edMonkeys have many social influences that make them compatible with a variety of animals. While in the wild, monkeys are most compatible with other primates such as capuchins, tamarins, and marmosets. Monkeys also form strong bonds with some larger mammals, such as lemurs, llamas, and horses.
Domestic animals like cats and dogs can also become good companions to monkeys. In addition, some birds make great friends with the primates as well, including macaws, macrones, lovebirds, and cockatoos.
