Standing up micro-naps
Dairy cows like those of the Naturellement Normande farm sleep intermittently, even standing up. They take micro-naps that represent about 8 hours of sleep. They do not bite the grass but surround it with their tongue to tear it off. The cows have 360° binocular vision and can move their eyes independently without having to move their heads. They communicate with each other with head and body movements and recognize their master's voice very well.
