Nine Lives

When a cat becomes a leader, they get nine lives and become a star.

But I don't see how they don't use up their lives so quickly. There's no way one could survive that long in a star.

So they become a star and return to their Clan, but having a star on board a planet can not be safe. How do they not burn up the whole world?

When they die, they implode and create a black hole. A black hole, now that's something that is definitely not safe to have on Earth.

Guess it discourages murdering your leadership. "Take me down and I take the whole planet down with me."
