tundrarunners are colored white or light gray, with darker gray and black markings, and red, orange or yellow eyes.
naturally they hunt in packs, which works well with the northern hunting techniques.
they run incredibly fast in short bursts, like cheetahs, but cant hold their speed over long distances.
they have long, thick fur for keeping warm in their cold habitat, and large paws for helping them walk in the snow.
theyre strict carnivores, eating anything other than meat will cause them to become sick.

Tundrarunners, Seodalis and Seo belong to me.
