Sagewhisker

Sagewhisker is a fluffy white she-cat with long whiskers.

Crookedstar's Promise

 * She is mentioned briefly when Brambleberry is introducing her new apprentice, Mudfur, to the other medicine cats.

Bluestar's Prophecy

 * Sagewhisker is the ShadowClan medicine cat during the time that Cedarstar is leader. She takes on Yellowfang as her apprentice, even though Yellowfang has already been trained as a ShadowClan warrior.


 * At a Gathering, Bluepaw sees Sagewhisker sitting next to Yellowfang. It is announced that Yellowfang is Sagewhisker's new apprentice.


 * Sagewhisker is not seen after that, so it is assumed that she either died or retired. Yellowfang takes Sagewhisker's place as ShadowClan's full medicine cat.

Night Whispers

 * Sagewhisker is first seen talking to Yellowfang and Fernshade in StarClan's territory. She's upset about Russetfur's death, saying that they should've sent a sign that the battle was not justified and should not have happened. When Bluestar appears, Sagewhisker is angry with her as well, because Bluestar agrees that the battle couldn't have been stopped, and yet, Bluestar didn't try to stop it. When Yellowfang intervenes, it is revealed that Sagewhisker, Yellowfang's former mentor, is still angry with her for kitting Brokenstar. Sagewhisker claims that she still thinks the battle is ThunderClan's fault and that Brokenstar wasn't ShadowClan's fault while Fernshade goes to fetch Russetfur.


 * When Flametail sleeps at the Moonpool, Sagewhisker and Palefoot introduce him to ShadowClan's StarClan. She reveals that StarClan is divided and doesn't want to tell Flametail anymore, but when Raggedstar appears, she tells Flametail that he must break his friendships and protect his Clan at all costs. Sagewhisker also hints that a war is rising between all the four Clans.
