There have been cats here on earth for a very very long time - much longer than dogs and wolves or bears. Cavemen probably tamed some of the smaller cats and let them live in the caves, where they could chase the rats, mice or snakes that tried to get in. One cat called the sabre toothed tiger was not a pet. It was as big as some cars today. Cavemen scared them away with fires they kept burning at night.
Lions are very strong cats.
The male lion may weigh 400 pounds or more. The female lion wieghs much less - usually no more than 300 pounds. A lions coat is sandy brown in colour. Male lions are the only members of the cat family that have manes. The mane is usually the same colour as the coat but can be black.
