A Family at War is the thirteenth and final episode of the third season of Meerkat Manor.
At nearly fifty members the Whiskers were the biggest group on the Manor. With Zaphod back, the family were at their strongest, but tensions run high between Rocket Dog and her competitive sister Maybelline, who narrowly missed out on the dominant position. While out foraging Rocket Dog and Maybelline compete over a freshly dug hole. Maybelline is eventually defeated and wanders off while making lead calls for her pups to follow. Instinctively half of the Whiskers follow her, leaving the others behind to forage. In the evening Rocket Dog returns home to find half of the family missing, including most of the pups.
The next morning Maybelline's group wake up to find the Zappa closeby. The two groups collide but Maybelline's group win and drive the Zappa off their territory. During the fight Lola had managed to save the Zappa's pups, providing hope for the family. Maybelline claims the stolen territory as her own and her group recieves a name, the Aztecs. It becomes apparent that the Whiskers would be permanently divided, but who would become Flower's successor was left unclear.
