Indoor-outdoor housing systems for a self-sustaining marmoset breeding colony.

Indoor-outdoor housing of three types was designed, constructed, used and evaluated for housing a breeding colony of common (Callithrix jacchus) and cottontop (Saguinus oedipus) marmosets. All types were relatively inexpensive to construct, required minimal care, simulated a natural environment and allowed for some isolation between units and between individual runs within units.
