The valley is inhabited by snow leopards, foxes ibex, Himalayan brown bear, musk deer, and Himalayan blue sheep. Snow leopards are protected within the Pin Valley National Park and Kibber Wildlife Sanctuary. The Lingti plains are home to animals such as yaks and dzos.
Over-hunting and a decrease in food supplies have led to a large reduction in the population of the Tibetan antelope, argali, kiangs, musk deer, and snow leopards in these regions, reducing them to the status of endangered species. The locals of Spiti do not hunt these wild animals due to their religious beliefs.
