The Youma Mob was formed in October 2014 when two Pandora females joined up with Baobab males and wild meerkats. During the first few months following the group's foundation there have been many immigrations and emmigrations, including that of wild unhabituated meerkats, making it difficult to keep track of all the members. The Baobab males had abandoned the group to join the Pandora and a few Pandora males had joined the Youma. One of the Pandora females briefly held dominance but since the begining of 2015, dominance has been unclear on both sides.
After one of the Pandora females left the group, the last Pandora female Mandela became the dominant female. Male dominance remained unclear, even after the Baobab males dispersed and Pandora males joined the group. By March 2015 dominance was unclear for both males and females.
