Cats are animals of habit（习惯）. They like to go to sleep at about the same time every day and for a certain length of time. They seem to have a natural clock inside them that tells them when to sleep.
Besides their regular sleep, cats take naps. Some scientists think that people should also take cat naps. The habit would do good to people's health. Cat naps help to build up energy in the body. Since cats have moods（情绪）like those of people, scientists believe that people can improve their moods and attitudes（态度）by catnapping. People might become happier and more active.
A lot of famous people take cat naps during the day. The naps would usually last 15-30 minutes. Winston Churchill took cat naps. So did a few presidents of the United States.
