Claudius laughs, and shakes his head. "A leader can still choose not to have kits, in my clan. Then some of the twolegs will have a vote to choose the leader after him. But it's a clan with very little trust between most of the twolegs. If it's unclear to them who the next leader will be, the twolegs in my clan will argue, and even go to war. So they try to prevent that by making leadership simple. The eldest son of the last leader is almost always made the next. It's a bad system, in fact, that the philosophers of other twoleg clans criticize. How are your leaders chosen?"
