Running Mouse (Mouse) is a skinny light brown tabby she-cat with shining golden eyes and long, muscular legs.
Timid, nervous, easily-excited, but fiercely loyal. She is submissive to her authorities and a extremely swift she-cat.
- Running Mouse is the ForeAlpha of the swift Flash Gang.
- She and Shoketa go to Blood Gang's camp for herbs and a little food, for theirs had dried up, and Shoketa goes to find the precious supplies. Mouse stays outside and chats for awhile, but Sally comes up and slices Razor's cheek, and she gets frightened. So frightened that she lunges forward and digs her claws into Sally's shoulders. Bright Shadow kicks her off, and stomps on her tail, making Mouse yelp and run back to camp. Flashback comments on how weak the ForeAlpha is.
