Caleb and the other rovers joined the Zulus Mob. All of the males competed for the position of dominant male, but Caleb remained a subordinate male and a regular rover during his stay. In July 2015 Caleb, Dis-Grace, Gobolino, Flammkuchen and Laurentina left the Zulus to form a subgroup called Tulus. All of the males except for Caleb returned to Zulus, leaving just the two members behind. Laurentina was pregnant at the time and gave birth in September 2015. Sadly she disappeared after that and was predated two weeks later. What became of her pups is unknown. Caleb returned to Zulus by the end of the month. He is still alive and living in Zulus today.
