CATSCats have long been valued by humans for
companionship and are the most popular companion animal. There are over
500 million domestic cats throughout the world. Descended from African
wildcats, they began to share homes with humans about 10,000 years ago.
cats are still similar in anatomy to wild cats, with strong, flexible
bodies, quick reflexes, sharp retractable claws and teeth adapted to
killing small prey. They have excellent hearing, sense of smell and
night vision.Cats are felids, which are mammals that include
lions, tigers, cougars, jungle cats, wildcats, mountain cats, sand cats
and other wild cats. They all share a common ancestor that lived around
6–7 million years ago in Asia.
