Felis catus[
The domestic cat[1][2] (Felis catus[2] or Felis silvestris catus[4]) is a small, usually furry, domesticated, and 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 often valued by humans for companionship and their ability to hunt vermin and household pests.
Cats are a cosmopolitan species and are found across much of the world.[38] Geneticist Stephen James O'Brien, of the National Cancer Institute in Frederick, Maryland, remarked on how successful cats have been in evolutionary terms: "Cats are one of evolution's most charismatic creatures. They can live on the highest mountains and in the hottest deserts."[163] They are extremely adaptable and are now present on all continents except Antarctica, and on 118 of the 131 main groups of islands – even on sub-Antarctic islands such as the Kerguelen Islands.[164][165] Feral cats can live in forests, grasslands, tundra, coastal areas, agricultural land, scrublands, urban areas and wetlands.[166] Their habitats even include small oceanic islands with no human inhabitants.[167] This ability to thrive in almost any terrestrial habitat has led to the cat's designation as one of the world's worst invasive species.[168] Despite this general adaptability, the close relatives of domestic cats, the African wildcat (Felis silvestris lybica) and the Arabian sand cat (Felis margarita) both inhabit desert environments,[4] and domestic cats still show similar adaptations and behaviors.[35]
