Sheep are quiet, unresponsive and slow. Sheep can't climb the steep slopes of the mountains. When they eat, they like to head down and eat short, sparse young grass that can't be eaten by large animals or goats. Goats are lively, responsive, and flexible in action. They like to ascend for food and can graze on steep slopes and mountains that sheep and other large animals cannot use. When goats and sheep are grazing at the same time, the goats always walk in front and eat high-quality grass first, while sheep slowly walk behind and can only eat inferior grass.
