Mountain clan is the smartest clan of the 4 main clans. They always have a good plan, and not to mention backup plans. They do things for their own benefit, and consider themselves the best out of all clans. These cats live in the mountains, and so developed larger rib cages for easier breathing. Mountain clan cats are usually gray, white, or black in color, to mix in with surrounding rocks. Quite often, they are mottled colored.
