Whitewater

Whitewater is a white she-cat with long fur and one blind, clouded eye. She is an elder of ShadowClan in Misty Paths and Betrayed.

Misty Paths
Whitewater is getting picked by Rowanstar and Crowfrost to go to the Gathering, and Ratscar asks if he can go. Whitewater rolls her eyes and nudges him away, claiming it's her turn to go. She goes to the Gathering with several other cats.

She is next heard of when Leopardpaw is complaining to himself that neither she or any cat else in the Clan will tell him any of the details about the so-called "Great Battle".

Betrayed
She is mentioned only once when Leopardpatch is thinking sadly of every cat who he missed, still in ShadowClan, waiting for him to come back.

Trivia

 * She is mistakenly called a "light silver she-cat with distinct white markings and blue eyes" in the allegiances of Betrayed.
