This is a fan fiction about Princess. Since I've only read up to book 3, I don't know what will happen to her in the real series. However, Princess has always been one of my favorite characters in the series, and it bothers me that Firestar leaves without telling his sister about it. So, here's what I think should happen to Princess. I hope you like it.
Princess had never gone very far beyond her fence before. The tabby cat twitched her tail a few times in a very nervous fashion. Her brother, Firestar, had not come to see her since those large monsters appeared, and she very much wanted to see how he was doing. Since she did not know where he lived, not exactly anyway, she simply stared out the windows, if her housefolk wouldn't let her out, or by the fence, if she were out.
It had been many weeks, though it felt like years. Her brother had never been away for so long without telling her. Not only that, but her son Cloudtail hadn't been to see her either. Though he didn't come as often as Firestar, and he usually brought Brightheart (after her initial shock at the cat's appearance, Princess and Brightheart had become very good friends), he would still come and visit whenever he could.
Finally, she had gotten word about them…though she still didn't see her brother or son. It was from a cat named Cody who lived a few houses down. She had been in the ThunderClan camp, and had become very good friends with Leafpaw. Though she couldn't tell much, she was able to say that all the Clan cats were leaving, going somewhere over the mountains. There was too much destruction in the forest.
"He left without saying good-bye?" Princess exclaimed when she heard about them leaving. She could only take the shock in small amounts, and at first could only be angry with her brother and son for going without telling her. She would hiss at her housefolk if they tried to pet her or pick her up, and could only munch moodily on her kibbles. As the facts settled in, her sorrow overcame her rage, and she stopped eating altogether.
Her housefolk took her to the vet's to be checked; for it seemed to them that something must be wrong with her. Nothing, it seemed, could possibly be wrong. Still, the veterinarian gave some liquid nutrients, which they would have to bottle feed their cat with. As the days went by, Princess's coat lost its pretty shine, and her eyes dimmed with depression. The housefolk were at a lost, and simply let Princess outside, hoping that the fresh air would make her feel better.
As soon as she stepped out, one thought entered Princess's mind. She could leave now, and go after her brother and son. Though her housefolk were kind, and the neighboring cats were nice, nothing would ever replace the bond of kinship she felt when she was with Firestar and Cloudtail. She wanted to be with her son and brother and their mates, she wanted to help him raise his kits, and she wanted to be a part of their lives. No matter where they went, she had to follow.
But not right now, or her owners would come out and get her before she could escape. Besides, she had to eat up and regain her strength. She did not know how to hunt, and she had to say good-bye to her housefolk and friends.
She said good-bye to Smudge (who had always known in his heart that Princess would end up like her brother: in the wild), she said good-bye to Cody (who told her exactly the direction that the Clans all went), and she said good-bye to the yard she had lived in for so long, and returned inside.
After one last meal inside (her people were so happy to see her eating that they gave her some chunks of meat as a treat) and one last cuddle with her housefolk, she meowed to be let out that night, and slipped away into the darkness.
