The Cave Men was founded in late 2011 by three JaXX females and three Lazuli males and was soon joined by an escaped pet meerkat. Dikkop establisted dominance however the two suboridnate females rejoined the JaXX. Male dominance past to Rufio after the death of Franz. Even after new Lazuli males joined the group the Cave Men had no successful litters, losing them within months of birth. In early 2013, the Dikkop disappeared after looking very ill for several day and the remaining males started to disperse.
The eldest of the females, Dikkop establisted dominance. Franz assumed the role of dominant male, however Franz soon died laving his younger brother Rufio became the next dominant male. In September however three more Lazuli males joined the group Snowy ousted Rufio from the dominant male position. In February 2013, Dikkop disappeared after looking very sick for several days and did not return. With no females left in the group, Snowy left to rejoin the Lazuli while the other males started to rove. In April 2013, Snowy rejoined the group however he didn't take dominance again.
