     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.
