Cats are animals of habit. They like to go to sleep 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 (定时的, 正式的) sleep, cats. take naps (打盹). Some scientists think that people should also take cat naps. The habit would do good to people's health. Cat-naps help build up energy (精力, 能量) in the body. Since cats have moods (情绪) like those of people, scientists believe that people can improve their moods and attitudes by catnapping. People might become happier and more active.
