Tell us about the cat
The cat, also known as the domestic cat or house cat to distinguish it from other felines and felids, is a small predatory carnivorous species of crepuscular mammal that is valued by humans for its companionship and its ability to hunt vermin, snakes, and other unwanted household pests. It has been associated with humans for at least 9,500 years. The house cat is the most popular pet in the world.
A skilled predator, the cat is known to hunt over 1,000 species for food. It can be trained to obey simple commands. Individual cats have also been known to learn on their own to manipulate simple mechanisms, such as doorknobs and toilet handles. Cats use a variety of vocalizations and types of body language for communication, including meowing, purring, "trilling", hissing, growling, squeaking, chirping, clicking, and grunting. They are also bred and shown as registered pedigree pets. This hobby is known as "cat fancy".
Until recently the cat was commonly believed to have been domesticated in ancient Egypt, where it was a cult animal. However, in 2004, the earliest known location of cat domestication was discovered to be ancient Cyprus, and a subsequent study in 2007 found that the lines of descent of all house cats probably run through as few as five self-domesticating African Wildcats (Felis silvestris lybica) circa 8000 BC, in the Near East.
Cat Senses
Cats have excellent night vision and can function at only one-sixth the light level required for human vision. This is partly the result of cat eyes having a tapetum lucidum, which reflects any light that passes through the retina back into the eye, thereby increasing the eye's sensitivity to dim light. Another adaptation to dim light is the large pupils of cats' eyes. Unlike some big cats, such as tigers, domestic cats have slit pupils. These slit pupils can focus bright light without chromatic aberration, and are needed since the domestic cat's pupils are much larger, relative to their eyes, than the pupils of the big cats. Indeed, at low light levels a cat's pupils will expand to cover most of the exposed surface of its eyes. However, domestic cats have rather poor color vision and can only see two colors: blue and green, and are less able to distinguish between red and green, although they can achieve this in some conditions.
Newcastle
Newcastle upon Tyne (often shortened to Newcastle) is a city and metropolitan borough of Tyne and Wear, in North East England. Situated on the north bank of the River Tyne, the city developed in the area that was the location of the Roman settlement called Pons Aelius, though it owes its name to the castle built in 1080, by Robert II, Duke of Normandy, the eldest son of William the Conqueror. The city grew as an important centre for the wool trade and it later became a major coal mining area. The port developed in the 16th century and, along with the shipyards lower down the river, was amongst the world's largest shipbuilding and ship-repairing centres. These industries have since experienced severe decline and closure, and the city today is largely a business and cultural centre, with a particular reputation for nightlife.
