Meerkat (suricate), Suricata Suricatta

New meerkat groups are often formed by evicted females pairing with roving males.
If the members of the alpha group are relatives (this tends to happen when the alpha female dies and is succeeded by a daughter), they do not mate with each other and reproduction is by group females stray-mating with roving males from other groups; in this situation, pregnant females tend to kill and eat any pups born to other females.
