Mouse catching cat

A mouse is terrible, and the head is as big as a small ball.

Once, the mouse hit a cat, the cat was very fat, and the mouse thought: "I haven't eaten for a few days, let me eat it." So the mouse was brave and rushed to the cat to fight with the cat. This cat is vulnerable. It turned out that this cat is a pet cat and has lost the ability to catch rats.

Just as we will not forget the knowledge of the previous knowledge and forget it.
