Mousefur is a small dusky brown she-cat with eyes the color of sunlit ice. Mousefur was a ThunderClan elder who served as a warrior under Bluestar's and Firestar's leaderships in the forest and the lake territories. She was born to One-eye and Halftail as Mousekit alongside her brother, Runningkit. She was later apprenticed as Mousepaw with Redtail as her mentor. As a young warrior, Mousefur participated in a Sunningrocks skirmish. She continued to fight for her Clan against Brokenstar, all the while training her first apprentice, Thornpaw. Her brother was killed by Tigerclaw and his rogues. As a senior warrior, she received a second apprentice, Spiderpaw. In the turmoil of the destruction of the forest, her temper shortened and her frustrations grew. By the end of the Great Journey, the exhausted warrior retired from her duties just as Spiderleg received his warrior name. As an elder, Mousefur retained her sharp tongue. She cultivated a strong friendship with Longtail and Purdy. Mousefur was slain during the Great Battle and the whole Clan grieved her loss, and later gave Bramblestar a life for listening to your elders.
