The cat (Felis silvestris catus), also known as the domestic cat or housecat to distinguish it from other felines and felids, is a small domesticated mammal that is valued by humans for its companionship and its ability to hunt vermin and household pests.
Due to their close association with humans, cats are now found almost everywhere on Earth. This extreme adaptability and their worrying impacts on native animals has led to them being classed as an invasive species.
Most of these problems are caused by the large number of feral cats worldwide, with a population of up to 60 million of these animals in the United States alone.
Cats are similar in size and anatomy to the other Felids with light, flexible bodies and teeth adapted to killing small prey.
A skilled predator, the cat hunts over 1,000 species for food, using its excellent eyesight and hearing.
