Cats are creatures of habit. They like m 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. Cats supplement their regular sleep with occasional catnaps. Some experts feel that human could also benefit from this habit.
    Catnaps help to build up energy in the body. They are al so a good way to overcome boredom. Since cats have moods similar to those of humans, some experts believe that people can improve their moods and attitudes by catnapping. People might become happier and more positive.
    A number of famous people have copied cats by taking catnaps during the day. The naps would usually last from fifteen to thirty minutes. Winston Churchill took catnaps. So did Presidents Harry Truman, John F. Kennedy, and Lyndon B. Johnson. These famous men were known for their energy, they were also able to work long hours, often into the night. Napping was their secret.
