Zaphod took some of his boys and went up to join with Maybelline and the Aztecs! Zaphod is the dominant male.
Rocket Dog evicted Cruise, Rocky, Petra, and Milley. Don't know if Animal Planet will use their real names though. Anyway those four females found three unstudied males(they weren't used to humans) and formed a new group, BB.
Several Whisker males joined Commandos and Maybelline's brother Zarathustra became the dominant male(Hannibal died a few months ago and Nikita died, hmm, 2 or 3 months ago.)
