Kit[]

Featherkit is born to Graystripe and Silverstream at Sunningrocks along with her brother, Stormkit.
Her mother, Silverstream, died giving birth (blood loss), despite Cinderpaw's efforts to save her, though she and her brother were barely saved by Yellowfang.
The kits are taken to ThunderClan to be with their father. They are nursed by Goldenflower, despite the fact she is already nursing Bramblekit and Tawnykit.
Soon after, RiverClan begins an argument with ThunderClan, saying that half-Clan kits usually go to their mother's Clan. Graystripe, not wanting to start a fight, takes Stormkit and Featherkit to RiverClan and stays there with them. They are first nursed by Greenflower, and later Mosspelt.
Featherkit and Stormkit are seen playing while Crookedstar mentions that Graystripe is trying hard to fit in.

She becomes an apprentice, as Mistyfoot as her mentor.
Featherpaw, Stormpaw, Mistyfoot, and Stonefur are taken prisoners by Tigerstar for being half-clan cats.
Kept in a old fox-den and nearly starved to death, but Tigerstar brings out Stonefur and the apprentices.
He wants them all killed but Stonefur mentions that his loyalty is for RiverClan and there was no need to all the killing.
Tigerstar wants Stonefur to kill the apprentices but he refuses.
The apprentices watch Darkstripe (clumsily) fight Stonefur but Tigerstar thinks he is too weak and orders Blackfoot to kill Stonefur.
Stonefur is killed and the apprentices report Stonefur's death to Mistyfoot.
The three are brought to ThunderClan.
Mistyfoot and Featherpaw are trained by Graystripe.
Both of the apprentices kill Bone, along with Bramblepaw, Tawnypaw, Ashpaw, and Fernpaw.
In the manga of Crookedstar's Promise, she is shown playing with her brother Stormpaw/fur.

Chosen to journey to the Sun-Drown place by Oakheart in StarClan.
Her brother Stormfur accompanies her because they are always together.
When Squirrelpaw is stuck in a fence, Feathertail and Tawnypelt get her out by making her fur slippery.

Explains to Brambleclaw that Crowpaw isn't so bad, he is just lonely.
The cats encounter a dog and Feathertail is trapped.
Crowpaw saves her by distracting the dog.
Develops a slight crush on Crowpaw, being the only one who understands him and sees past his stubborness.
She wants to prove that Crowpaw is as brave and strong as any Warrior but Brambleclaw wanted to call him a stupid furball.
Soon, her affection for Crowpaw becomes more apparent; almost always together.
Stormfur is angered that Feathertail is nearly breaking the code as their parents did but she is very defensive, and they start to argue.
