Cat

The domestic cat[1][2] (Felis catus[2] or Felis silvestris catus[4]) is a small, usually furry, domesticated, carnivorous mammal. It is often called the housecat when kept as an indoor pet,[6] or simply the cat when there is no need to distinguish it from other felids and felines. Cats are valued by humans for companionship and their ability to hunt vermin and household pests. Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small game. They can see in near darkness. Like most mammals, cats have poorer color vision and a better sense of smell than humans. Despite being solitary hunters, cats are a social species, and cat communication includes the use of a variety of vocalizations (meowing, purring, trilling, hissing, growling and grunting) as well as cat pheromones and types of cat-specific body language.[7] Cats have a rapid breeding rate. Under controlled breeding, they can be bred and shown as registered pedigree pets, a hobby known as cat fancy. Failure to control the breeding of pet cats by spaying and neutering, and the abandonment of former household pets, has resulted in large numbers of feral cats worldwide, with a population of up to 60 million of these animals in the United States alone, requiring population control.[8] Since cats were cult animals in ancient Egypt, they were commonly believed to have been domesticated there,[9] but there may have been instances

of domestication as early as the Neolithic.[10] A genetic study in 2007 revealed that domestic cats have descended from African wildcats (Felis silvestris lybica) c. 8000 BCE, in the Middle East.[9][11] According to Scientific American cats are the most popular pet in the world, and are now found almost every place where people live. Fur is a synonym for hair, used in reference to non-human animals, usually mammals; particularly those with extensive body hair coverage. The term is sometimes used to refer to the body hair of an animal as a complete coat, also known as the "pelage". Fur is also used to refer to animal pelts which have been processed into leather with the hair still attached. The words fur or furry are also used, more casually, to refer to hair-like growths or formations; particularly when the subject being referred to exhibits a dense coat of fine, soft "hairs." Animal fur, if layered, rather than grown as a single coat, may consist of short ground hair, long guard hair, and, in some cases, medium awn hair. Mammals with reduced amounts of fur are often called "naked", as in The Naked Ape, naked mole rat, and naked dogs. An animal with commercially valuable fur is known within the fur industry as a furbearer. The use of fur as clothing and/or decoration is considered controversial by some people: most animal rights advocates object to the trapping and killing of wildlife, and to the confinement and killing of animals on fur farms. Fur has been a major challenge for 3D computer graphics artists due to its visual complexity and physical properties. The first movie which made extensive use of CGI fur was Pixar's 2001 film Monsters, Inc..
