Pairing female Macaca fascicularis (1998)

Kurth, B., Bryant, D.

Abstract

Twenty-nine previously single-caged adult female long-tailed macaques were paired with each other in vertical, double-cage configuration. Partners were compatibly in 81% of cases. Neighboring pairs were often charging each other across the grid panel. ... To avoid this, pairs were transferred to a horizontal configuration after the first month.
