The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, carnivorous mammal. It is often called the housecat when kept as an indoor pet, 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 pheromones and types of cat-specific body language.
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, while in Japan they are caught and disposed of.
Since cats were cult animals in ancient Egypt, they were commonly believed to have been domesticated there, but there may have been instances of domestication as early as the Neolithic.
A genetic study in 2007 revealed that domestic cats have descended from African wildcats (Felis silvestris lybica) c. 8000 BCE, in the Middle East. According to Scientific American cats are the most popular pet in the world, and now found almost every place where people live.
The average life expectancy for male indoor cats at birth is around 12 to 14 years, with females usually living a year or two longer. However, there have been reports of cats reaching into their 30s, with the oldest known cat, Creme Puff, dying at a verified age of 38. Feline life expectancy has increased significantly in recent decades. Having a cat neutered or spayed confers some health benefits, since castrated males cannot develop testicular cancer, spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer. The lifespan of feral cats is hard to determine accurately, although one study reported a median age of 4.7 years, with a range between 0 to 8.3 years.
Cats can suffer from a wide range of health problems, including infectious diseases, parasites, injuries and chronic disease. Vaccinations are available for many of these diseases, and domestic cats are regularly given treatments to eliminate parasites such as worms and fleas.
In addition to obvious dangers such as rodenticides, insecticides and herbicides, cats may be poisoned by many chemicals that are usually considered safe by pet owners. This is because their livers are less effective at some forms of detoxification than those of many other animals, including humans and dogs. Some of the most common causes of poisoning in cats are antifreeze and rodent baits. It has also been suggested that cats may be particularly sensitive to environmental pollutants. When a cat has a sudden or prolonged serious illness without any obvious cause, it is possible that it has been exposed to a toxin.
Pisica domestica (Felis catus) se trage din formele salbatice Felis silvestris lyberica. Dupa ipoteza lui Haltenorth, aceasta specie a fost domesticita in Egipt din cele mai vechi timpuri, tara in care pisica a fost inaltata pe piedestalul divinitatii, fiind obiectivul de veneratie al faraonilor. Din Egipt, pisica a fost introdusa in Europa in sec al V - lea unde s-a raspandit rapid, fiind cel mai eficient mijloc de combatere a sobolanului brun (Rattus rattus).Aici au avut loc frecvente incrucisari cu alte pisici salbatice, de aceea nu este usor astazi sa se explice descendenta pisicii noastre domestice.
