Cow

The total mass of all cows living on Earth is approximately three times the weight of all people.

As I said, cows moo for various reasons: fear, distrust, anger, hunger or suffering. Each cow has its own way of asking questions - either with a look or with a strange low moo. Once, one very cold February night, I was awakened from a deep tired sleep by a cow moo

It is difficult to describe exactly how cows see colors, but the location of the cells in the retina of the cow's eye makes it possible to say with certainty that they, although very weakly, can distinguish colors such as red and green, blue and yellow, black and white. Cows don't see colors as clearly as humans.
