Cats are creatures 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. Cats increase their regular sleep with occasional cat naps（打盹）. Some experts feel that humans could also benefit from this habit. Cat naps help to build up energy in the body. They are also a good way to get rid of trouble! Since cats have the same moods（情绪）as humans, some experts believe that people can improve their moods. People might become happier.
A number of famous people have copied cats by taking cat naps during the day. The naps would usually last from 15 to 30 minutes. Winston Churchill took cat naps. 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.

Is it true that cats have nine lives? One 4-year-old American cat named Sugar definitely seems to have more than one. Sugar fell from the 19th floor of her owner’s home in Boston last month and was only hurt a little on her chest.
“This story isn’t much of a surprise,” said Jake Socha, a scientist at Virginia Tech University, US, in an interview with the BBC. “There have been lots of records of these cats surviving.”
Back in 1987, scientists studied 132 cats. All of them had been brought to a vet’s clinic in New York after falling from tall buildings. Around 90 percent of these cats were alive after their fall and only 37 percent had been seriously injured.
“Being able to survive falls is a critical thing for animals that live in trees, and cats are one of them,” said Socha.
Cats have developed special body structures to survive accidental falls. Their legs are muscular. This can protect their bones from breaking, Professor Andrew Biewener from Harvard University told the BBC. Cats can also spread out their legs like a parachute to reduce their falling speed, he said.
The strange part, according to scientists, is that cats have a better chance of survival if they fall from higher than seven stories. This is because cats have a good sense of which way is down. They can twist their bodies as they fall to make sure they land on their feet. A higher fall means more time for the cat to change its body position.
However, you should not throw your cat out of the window to see how this works. Most pet cats are overweight nowadays. They are not fit enough to change their position in midair, warned Steve Dale, an American cat behavior scientist.
“This cat (Sugar) was lucky,” Dale said. In fact, most cats would suffer serious lung damage, a broken leg or a broken jaw or teeth damage, he said.

Cats are very smart. They are one of the smartest animals. The brain of a cat is large. It is highly developed. This may be why cats have good memories. Cats remember kindness and cruelty. It is a good idea to treat a cat well. Cats can “speak” too. They meow for attention. Often they stand by a door. Then they meow. Then they look over their shoulders. They want to see if their owners are coming. Cats make other noises also. They purr(猫发出的咕噜声)when they are happy. They hiss when they are angry.
Cats have a lot of pride. They don’t usually do silly tricks. Almost all cats want to have their own way. They are mostly true to only one person. They don’t switch loyalty easily. Cats were free in the wild. They want to stay that way. They like to be their own masters. When a cat is left alone, it can go back to caring for itself. It can live in the wild again. This is different from dogs. Dogs will switch their loyalty. At one time dogs were loyal to the leaders of their packs. Now, they will transfer allegiance(忠诚)to their owner. They do not like to be alone.
With kindness, a cat can be trained. Cats can learn to do many things. Some cats can learn to open doors. Some can ring doorbells. Some can even turn on water tap. Then they take a drink. Cats are very smart. Before drinking, they put a paw in the water. They test whether the water is hot or cold.
