Owlwhisker

Owlwhisker is a pale, light brown tabby tom with yellow teeth.

Dawn

 * When the traveling cats, Crowpaw, Brambleclaw, Squirrelpaw, Stormfur, and Tawnypelt, return to the forest, they cross into WindClan territory and run into Owlpaw. Crowpaw calls him Owlkit and says he's too young to be out of the nursery. Owlpaw remarks by saying he's Owlpaw now. He doesn't believe Crowpaw is really him, since Crowpaw disappeared moons ago. However, after sniffing him, Owlpaw says that Crowpaw smells strange. Crowpaw then tells him he's been on a long journey and needs to talk with Tallstar. After this, a WindClan warrior named Webfoot arrives and takes Crowpaw back to their camp.

Starlight

 * Owlpaw is comforted by a RiverClan queen when he first hears of Tallstar's death. Later, he is on the WindClan patrol with his mentor, Tornear. After a brief skirmish over where the boundary line would be, the patrol brings Leafpaw to their camp so she could heal their sick elders.

Twilight

 * Owlpaw becomes a warrior, named Owlfeather, but this was later changed to Owlwhisker.

The Sight

 * Owlwhisker is not seen, but is mentioned to be one of the cats helping to chase away the dogs from WindClan camp.

Dark River

 * He is on the patrol that finds Leafpool, Jaypaw, and Brambleclaw, who wants to speak with Onestar about the "upcoming battle" with RiverClan. During the battle with WindClan, he engages Brook in combat, but is defeated by the mountain cat.

Eclipse

 * He, along with Ashfoot and Harespring, find Brambleclaw, Sandstorm, Hollypaw, and Brackenfur coming to talk with Onestar. Owlwhisker and his patrol turn them down. Owlwhisker remarks that ThunderClan needed to stop coming onto WindClan territory as they please.

Sunrise

 * He is on the dawn patrol when Hollyleaf, Lionblaze, and Jayfeather come to see Crowfeather. When Lionblaze angrily crosses the border, Owlwhisker demands what he thinks he's doing. When Lionblaze demands to see Crowfeather, and fluffs out his fur to twice his size, Owlwhisker's voice becomes shrill as he tries to hide his fear. He tells him they will fetch Crowfeather, but that he can wait on his own side of the border.

The Fourth Apprentice

 * Owlwhisker now has an apprentice, Whiskerpaw.

Fading Echoes

 * When two apprentices, Dovepaw and Ivypaw, sneak into WindClan so Dovepaw can visit Sedgewhisker, Weaselfur wakes up the rest of WindClan. Once Onestar hears what happened, he orders Leaftail, Owlwhisker, and Harespring to search the territory for any more signs of ThunderClan. The three cats leave instantly.

Sign of the Moon
His apprentice has becomes a warrior, named Whiskernose.

The Forgotten Warrior

 * When Sol goes into the tunnels to tell WindClan to attack ThunderClan, Owlwhisker is skeptical, and asks how WindClan can trust him, and asks how they would know that he hasn't told ThunderClan to attack them. Sol snorts that he has done just that in order to gain trust from ThunderClan warriors, but it'll be WindClan that he'll be leading into ThunderClan territory. Then Owlwhisker hears Ivypool move a pebble. Owlwhisker growls and inquires if someone is there and then demands the cat show themself.
 * Later, he is seen fighting with Dovewing in the battle in the tunnels. Dovewing charges into Owlwhisker and shoves him toward the nearest tunnel opening. Owlwhisker pushes back, but his paws are unsteady, and after a few heartbeats he turns and limps away.
