Mountain-Kin territory is large, seeing as it is the largest group of cats of these new four. There is twice as many cats in Mountain-kin as there are in Forest-Kin, Breeze-Kin, and Creek-Kin. Size doesn't matter, because they don't have as much territory problem like the plans. They have much larger territories and plentiful prey. Mountain-Kin's Camp is on flat ground hidden deep in the mountain, while they have two smaller camps just at the edge of the mountains closer to the rest of the Kin Cats. The leader of Mountain-Kin and his deputy often move from camp to camp, and a powerful warrior is put in charge while away. Mountain-Kin borders with Forest-Kin to the south, and Breeze-kin to the east. Consists of mostly pine trees.

Prey: All sorts of birds, including eagles that live higher up in the mountains, squirrels, and occasionally Owls and Rabbits are a good treat.
