History
Princess is a kittypet that lives in the Twolegplace on the outskirts of ThunderClan territory. She is Firestar's sister. When she gives birth to a litter of kits, she gives her first-born son to ThunderClan, dubbing him Cloudkit. She feels Twolegs shouldn't decide her kit's fate. She wants to decide the future of her own kit. He later becomes Cloudpaw and Cloudtail, successively. She leaves somehow between The Darkest Hour and Midnight, though she is not mentioned in Firestar's Quest
