Lions are members of the cat family. The average length of a grown-up lion is about nine feet and they weigh between 400 and 500 pounds. The males are larger than the females. People who hunt lions can always tell whether they are tracking a male or female by the size of the tracks. The male has much larger front feet than the female.
The lion's voice is a roar or a growl. Unlike other cats, it doesn't purr, and rarely climbs trees. Unlike other cats, too, it takes readily to deep water. Lions feed on grazing animals, so they live in more or less open country and not in forests. And because they drink once a day, they always live near some supply of water. Lions rest by day and do their hunting by night. Lions may live singly, or in pairs, or in groups of four to a dozen which are known as "prides." The main food supply of lions comes from zebras, gazelles, and antelopes. Sometimes a lion will attack a giraffe, but it won't attack an elephant, rhinoceros, or hippopotamus. When a lion isn't hungry, he pays no attention to other animals.
When hunting, a lion may lay hidden until an animal passes close by, or it may crawl and wiggle up to its victim and then make a sudden rush. When it makes that rush, it can go as fast as 40 miles an hour!
