Abstract

General recommendations for the species-adequate housing of marmosets and tamarins. Single caging is unsatisfactory for these highly social animals as they soon lose condition, appear nervous, are often more susceptible to disease, and may even die. As mature individuals are hostile to unfamiliar members of their own sex, the best strategy is to remove the oldest same-sex siblings from the family group and pair them together. .. Gang caging same-sex individuals is not advisable because it is an unnatural social grouping for these species and can lead to serious fighting (p. 565).In same-sex groups females tend to be more aggressive than males. Marmosets my circle repetitively or weave where they are in small, barren cages [p.572].
