Habits
Often in the valley shrubs and tall grasses, sometimes also entered the field. Nocturnal animals, the main activities in the twilight, and more individual activities. Action is very sensitive, good at concealment is generally not far from the habitat. Of plant leaves, stems and berries for food, also eat grass. After wading a temporary loss of ability to walk, this time were often captured. Under normal circumstances activities alone, only to estrus in pairs of male and female come together only Xunshi, went their separate ways after mating. That retains many original features of the deer, but also a small body of the original ruminant animals, in evolutionary biology research very valuable.

Population Status
Small mouse deer habitat by human activities impact, livestock trampling and man-made construction of small mouse deer severely damaged than the hidden, in addition it also threatened by hunting, feeding its people for meat and killing them. The distribution in our country because it is the edge of its distribution area, so area is very small, about 100km2, only in Xishuangbanna Mengla Shang, Meng Yuan, a few other places Mengla view, very few, it is estimated less than 100.
