Who is the superstar of the cat world? It has to be Uncle Cat. Uncle Cat is a fat white cat living in the
countryside of Japan. He is already nine years old, as old as our 50-year-old uncle in cat years. That's why
he gets the nickname (绰号) Uncle Cat.
Uncle Cat is a lazy cat. He often half shuts his eyes and lies in the sun. It makes him look relaxed and
peaceful. He also enjoys himself in a basket, so he has another name: Basket Cat.

the internet. They make people from all over the world to know and love this cute cat.
