Mousewhisker/Main article

Mousewhisker is a gray-and-white tom with green eyes.

Mouse is born to Daisy and Smoky, alongside his littermates, Berry and Hazel. He comes to ThunderClan as a kit and later becomes an apprentice, being trained by Spiderleg and named Mousepaw.

He tries to impress his mentor by catching squirrels during hunting patrols and one assessment, which leads to Cinderpaw breaking her leg after she falls while helping him come down from a tree.

He becomes a warrior named Mousewhisker, and he later becomes a mentor to Bumblestripe. He trained in the Dark Forest, but during the Great Battle he found out that they were tricking them, and fought for the Clans.

The New Prophecy

 * Mouse is born to Daisy and Smoky of the Horseplace, along with his siblings Berry and Hazel. Not wanting the Twolegs to take her kits, Daisy leaves the Horsesplace and is found on ThunderClan territory with her three kits. Firestar allows them to stay in the Clan, and Mouse is renamed Mousekit. He and his littermates are caught in the medicine den by Brightheart, and later he chases a butterfly with Hazelkit, and Mousekit tells Leafpool a tortoiseshell cat told them they could chase it. Daisy is terrified after the battle against the badgers and decides to leave ThunderClan and return to the Horsesplace, much to Mousekit and his siblings dismay. Brambleclaw and Cloudtail convince Daisy to come back to the Clan, and the kits are ecstatic.

Power of Three

 * Mousepaw is now an apprentice, his mentor being Spiderleg. During a Gathering, he shows Lionpaw around, and Mousepaw appears to have a little crush on Minnowpaw of RiverClan. Mousepaw and Cinderpaw are assessed to catch as much prey as possible. Determined to show his mentor he can catch a squirrel, Mousepaw climbs the Sky Oak, however he freezes high up, and Cinderpaw has to help him climb down. She ends up falling out of the tree and breaking her leg. He eventually receives his warrior name, Mousewhisker, along with his siblings Berrynose and Hazeltail.

Omen of the Stars

 * Mousewhisker is now a mentor to Bumblepaw. When Dovepaw tells the Clan about the brown animals blocking the stream, Mousewhisker sarcastically asks if they were Twolegs who had sprouted wings. His apprentice later becomes a warrior named Bumblestripe. Mousewhisker and Cherrypaw accidentally eat hemlock, and are saved by Cinderheart. He begins training in the Dark Forest, and goes to the WindClan border with some other trainees to practice battle moves. When The Great Battle begins, he is hiding beneath a bush with Birchfall and Blossomfall, until Ivypool convinces them to fight for the Clans.

Super Editions

 * In Bramblestar's Storm, Mousewhisker attempts to help Cherryfall when she gets stuck on a beam in the abandoned Twoleg nest, but he accidentally causes her to fall on Bramblestar, and he apologizes to her. After evacuating camp and setting up in the tunnels, he is often seen helping his Clan, and he fights beside Stoatfur in the battle against the badgers.

Novellas

 * In Dovewing's Silence, Mousewhisker and the other former Dark Forest trainees struggle to regain the trust of their Clanmates, and they all swear an oath of loyalty to ThunderClan. Dovewing patrols with him and the rest of the trainees, when Cherrypaw and Molepaw purposefully lead them into the danger of a trapped fox. After they kill the fox, the apprentices apologize and the rest of the Clan forgives Mousewhisker and the former trainees.

 * In The Sight, he was said to be eating in the camp, but then, a few pages later, he was said to have ran into camp with a patrol.
 * He is said mistakenly to be Cherryfall's brother, when he is in fact her uncle.
 * Birchfall, Mousewhisker, and Blossomfall are mentioned to have fought on the side of the Dark Forest, when in fact, they hid when the battle started until Ivypool convinced them to fight for the Clans.
