Fire and Ice
Fireheart keeps visiting his sister Princess while she is pregnant with a large litter of kits. Once they are born, the next time Fireheart visits her, Princess hands him a fluffy white kit. She says that this is her firstborn kit and she wants Fireheart to make him a hero much like himself.

Fireheart takes the white kit back to camp, and the Clan is shocked to hear that the kit is a kittypet. Many start to turn away from Fireheart. He is yelled at by Bluestar, but she agrees to keep the kit in ThunderClan, and names him Cloudkit. Fireheart takes Cloudkit to Brindleface, one of the nursing queens, and, since she has plenty of milk and she is willing to foster him, Cloudkit goes under Brindleface's care, and immediately befriends Ashkit and Fernkit, Brindleface's two surviving kits.

When he is a little older, Cloudkit forms a bond with the elders and they admire him. Later, in the cold, Cloudkit, Ashkit, and Fernkit go missing. The Clan is frantic and Fireheart finds them, and Cloudkit even has a skinny vole that he had caught. Fireheart scolds the kits, and they even find deathberries, but Cinderpaw stops him from eating them. They are taken home, and Bluestar is very angry, but lets Cloudkit put his vole on the fresh-kill pile.
