Hello! My name is Lisa, and I am a lioness. I live on the open grasslands of Africa with my family. Lions living in a group are called a pride.

My father is strong and powerful. He and his cousin are the leaders of our pride. The other members are my mother, her sisters, and their children.

The area where a pride lives is big! We roar (咆哮) to tell each other where we are and to warn strangers to stay away.

Meet my new baby brother. His name is Leon. See the spots on his fur? We lions are born spotted or striped (有条纹的). As we grow older, the spots gradually disappear.

Lionesses usually spend their entire lives with their birth pride, but Leon will leave when he is about three years old. He’ll run around with a male (雄性的) friend or relative for a few years until they take over a pride of their own.

But for now, we have lots of fun together. We often play and fight for hours, which can help us practice skills that we will need for hunting. )

We lions keep ourselves very clean. Just like a house cat, I clean my fur (毛with my tongue. We clean for each other, too, to show we’re friends.

Lions like to sleep for most of the day. We hunt in the cool evening. Female (雌性的) lions hunt more often than male lions. We work together as a team. At the right moment, we attack and kill our prey. Then we share it. Male lions usually eat first. Females eat next. Baby lions are the last to eat. The smallest one gets the least food.

Since we are full, it’s time to go to find a nice place for a sleep. Bye!
