Mule deer are known as browsers. From late spring to early fall, mule deer gain weight and build fat reserves by feeding heavily on broad-leafed plants and grasses. During the winter and early spring, when there is little forage available, their diet is mostly leaves, stems and buds.

The body is unable to complete its ATP formation cycle so they create muscular contractions. This causes the limbs to become stiff and difficult to manipulate.
Rigor Mortis usually starts taking place right after someone dies and lasts for about 72 hours depending on the temperature in the room that the death occurred in. The process of Rigor Mortis takes place mostly because the muscles cannot relax after someone dies. The bones in the personâs body start to actually contract within themselves and the skeletal muscles start to do the same.
