Yellowfang is the medicine cat of ThunderClan. In this scene, she has inhaled a lot of smoke from a forest fire and hasn't eaten in over two days. She is an old cat; found by Fireheart in the medicine den. During the fire, she had followed Fireheart to save two elders, Halftail and Patchpelt, but they had been separated by a falling tree and she had to retreat back to their burning camp. As she realized she was about to die, she dragged herself back into her den and was found two days later by Fireheart in this scene. Yellowfang has a RASPY and CHOKED voice, as if having a very sore throat (because she inhaled too much smoke and is dying).
