    At the age of six weeks, Lilo seemed to be a perfect family pet. But as he grew up, he became aggressive ( 富于攻击性的). One day, as his 9-year-old owner went close, Lilo jumped at her angrily. The girl’s arm got hurt badly. It’s unusual for a family pet to hurt its loving owner. But Lilo should never have been anyone’s pet. He was actually a tiger.

There are thousands of tigers, lions and other big cats kept as pets in American homes.“People love the idea of owning something wild and special,”says Nicole Paquette of the Animal Protection Institute.“But they have no idea how hard it is to take care of them.”

Tigers like Lilo can grow to weigh 650 pounds. They are strong and powerful. Each year many people are hurt or killed by pet tigers and other big cats.

The situation can also be deadly for the big cats themselves. They often end up in small and dirty cages. Living in dirty conditions, the cats become sick and often more aggressive. Many of them die. Others are sold to roadside zoos or to hunting ranches (狩猎牧场).

Shirley Minshew works to help send some big cats to sanctuaries ( 鸟兽保护区). But as Minshew says,“Most of these sanctuaries are already full.”So are big city zoos.

The only way to solve the problem is for people to stop buying these animals.“Although they can be kept in cages, they will never be like a dog or a cat,”says Paquette.“They are wild — and they should be allowed to stay that way.”
