This video segment from Nature describes cats as independent, mysterious and aloof. While they have been domesticated for more than four thousand years, they are still powerful predators and survivalists. Cats have a reputation for being uncontrollable and leading solitary lifestyles, yet they compete with dogs as the most popular pet in America. Cats live in thirty percent of American households; however, they still demonstrate characteristics of creatures of the wild. Their hunting habits, for example, parallel those of lions, cheetahs and tigers.
