Daisydust

Daisydust used to be a young and talented healer, trained one apprentice in this role and very devoted. However, her parents had their second litter, the two died along with her new siblings. Only Flarekit lived, and Daisydust stepped down as a healer to watch over her brother. When he became old enough to train as a warrior, Daisydust decided to follow the life of a standard warrior. Eucalyptussnooze was fine on her own and might get an apprentice of her own soon, so Daisydust wasn't needed. 

During her last moments as a healer, she fell for a Riverclan cat and became secret mates with her until Team Rocket raided the forest. The riverclan cat went missing and joined Rocket. The two broke up and haven't talked to one another since.

Tallest cat in Thunderclan.
