Drie DoringCassia(VDM051) was born on August 16, 1999 in the Drie Doring Mob. His mother was Mabili, the dominant female of the group, and his father was an unknown male, possibly the current dominant male. His litter-mates are mostly unknown, however it is known he had a brother named Burgan(VDM049). The brothers survived their first year and became adults. As an adult, Cassia was expected to take on adult meerkat responibilities like caring for the pups and taking his turn at sentry duty. None of the females in the mob could mate with Cassia, being his sisters and cousins, so he had to look elsewhere for an unrelated female to mate with him. Cassia and Burgan both stayed in the Drie Doring for two years before they finally left after coming across two evicted females from the Lazuli in December 2001.
The meerkats formed a new breeding group called the Moomins Mob. Burgan took up dominance of the group being the biggest and strongest of the two males. One of the Lazuli females named Grumpy took female dominance of the group. Before dominance was established, Cassia mated with the other female named Sleepy. She gave birth on December 9, 2002 Moomintroll, Snufkin, Sniff, Little My and Fillyjonks. They were the first pups ever born in the Moomins and the only litter the small group could raise during their first year of existance. Being a subordinate male, Cassia was not allowed to breed with either of the Lazuli females despite the fact they were unrelated to him. So Cassia started to take to roving again. He remained in the Moonins for almost two years before he finally disappeared after taking to roving on Novermber 3, 2003.
