The cat (Felis silvestris catus), also known as the domestic cat or house cat to distinguish it from other felines, is a small carnivorous species of nocturnal mammal that is often valued by humans for its companionship and its ability to hunt vermin. It has been associated with humans for at least 9,500 years. This is a furry animal that purrs and meows: a small domesticated mammal that has soft fur, sharp claws, pointed ears, and, usually, a long furry tail, and makes characteristic purring or meowing sounds. Cats are widely kept as pets or to catch mice. Cats typically weigh between 2.5 and 7 kg (5.5�16 pounds); Cat senses are attuned for hunting. Cats have highly advanced hearing, eyesight, taste, and touch receptors, making the cat extremely sensitive among mammals. Cats night vision is superior to humans although their vision in daylight is inferior. Cats are classified as obligate carnivores, predominantly because their physiology is geared toward efficient processing of meat, and lacks efficient processes for digesting plant matter. Similarly as with its teeth, a cat s digestive tract has become specialized over time to suit meat eating, having shortened in length only to those segments of intestine best able to break down proteins and fats from animal flesh. For cats, life in close proximity with humans (and other animals kept by humans as pets) amounts to a symbiotic social adaptation which has developed over thousands of years. When engaged in feline-to-feline combat for self-defense, territory, reproduction, or dominance, fighting cats make themselves appear more impressive and threatening by raising their fur and arching their backs, thus increasing their visual size. Domestic cats, especially young kittens, are known for their love of play. This behaviour mimics hunting and is important in helping kittens learn to stalk, capture and kill prey.
