News is information about current events. Journalists provide news through many different media, based on word of mouth, printing, postal systems, broadcasting, and electronic communication.
Common topics for news reports include war, government, politics, education, health, the environment, business, and entertainment, as well as athletic events, quirky or unusual events. Government proclamations, concerning royal ceremonies, laws, taxes, public health, and criminals, have been dubbed news since ancient times.
Humans exhibit a nearly universal desire to learn and share news
Technological and social developments, often driven by government communication and espionage networks, have increased the speed with which news can spread, as well as influenced its content. The genre of news as we know it today is closely associated with the newspaper, which originated in China as a court bulletin and spread, with paper and printing press, to Europe.
Evidence suggests that cultures around the world have found a place for people to share stories about interesting new information. Among Zulus, Mongolians, Polynesians, and American Southerners, anthropologists have documented the practice of questioning travelers for news as a matter of priority. Sufficiently important news would be repeated quickly and often, and could spread by word of mouth over a large geographic area. Even as printing presses came into use in Europe, news for the general public often travelled orally via monks, travelers, town criers, etc.
Cats have excellent night vision and can see at only one-sixth the light level required for human vision.
Cats conserve heat by reducing the flow of blood to their skin and lose heat by evaporation through their mouths. Cats have minimal ability to sweat, with glands located primarily in their paw pads, and pant for heat relief only at very high temperatures (but may also pant when stressed).
Cats are obligate carnivores: their physiology has evolved to efficiently process meat, and they have difficulty digesting plant matter. In contrast to omnivores such as rats, which only require about 4% protein in their diet, about 20% of a cat’s diet must be protein. Cats are unusually dependent on a constant supply of the amino acid arginine, and a diet lacking arginine causes marked weight loss and can be rapidly fatal. Another unusual feature is that the cat cannot produce taurine, with taurine deficiency causing macular degeneration, wherein the cat’s retina slowly degenerates, causing irreversible blindness.
A cat’s gastrointestinal tract is adapted to meat eating, being much shorter than that of omnivores and having low levels of several of the digestive enzymes needed to digest carbohydrates. These traits severely limit the cat’s ability to digest and use plant-derived nutrients, as well as certain fatty acids. Despite the cat’s meat-oriented physiology, several vegetarian or vegan cat foods have been marketed that are supplemented with chemically synthesized taurine and other nutrients, in attempts to produce a complete diet.
A cat has absolute emotional honesty: human beings, for one reason or another, may hide their feelings, but a cat does not. Ernest Hemingway
Domestic cats use many vocalizations for communication, including purring, trilling, hissing, growling/snarling, grunting, and several different forms of meowing. By contrast, feral cats are generally silent. Their types of body language, including position of ears and tail, relaxation of the whole body, and kneading of the paws, are all indicators of mood. The tail and ears are particularly important social signal mechanisms in cats; for example, a raised tail acts as a friendly greeting, and flattened ears indicates hostility.

In ancient Egypt, cats were sacred animals, with the goddess Bastet often depicted in cat form, sometimes taking on the war-like aspect of a lioness. The Romans are often credited with introducing the domestic cat from Egypt to Europe; in Roman Aquitaine, a first- or second-century engraving of a young girl holding a cat is one of two earliest depictions of the Roman domesticated cat.
