Having a cheetah as a pet in the house? Does it sound scary to you? But for a family in South Africa, one cheetah is treated as a VIP (Very Important Person) in the house.

The big cheetah is named Jolie, after the film star Angelina Jolie.      小题1:     She can often be found eating from the kitchen table, taking a short sleep on the sofa, or even sleeping on Lucy and Jeff’s bed. The big cat also sleeps and plays with the Browns’ other pet, the more usual one — a sheepdog (牧羊犬).      小题2:

However, a cheetah is always a cheetah.      小题5:    “She makes a lot of mess in the house, urinating (小便) everywhere and chewing everything. It’s her wild instincts (本能),” said Mrs Brown.

There might be some problems of having a cheetah as a pet in the house, but some unusual fun must also be waiting ahead.
