Provision of manipulable objects to cynomolgus macaques promotes species-typical behavior

A different pet toy was provided to each [single-caged] monkey during six weeks. Self-directed abnormal behavior was reduced or eliminated in all subjects in the presence of objects but increased after removal of the toys.
