Abstract
Maternal retrieval of 87 young representing 42 litters of the African bush Karoo rat Otomys unisulcatus F. Cuvier, 1829 was studied in the laboratory. All 17 females studied retrieved young by nipple-clinging, but ten females also mouth-carrying was poorly developed, as young were carried by various parts of the body in a non-stereotyped manner. Mouth-carrying in otomyine rodents is unusual; all other species previously studied use nipple-clinging exclusively.
