In English
In the days of Emperor at , an infectious disease appeared and gained ground quickly. It was reported that the disease spread through rats and so, each house was supplied a cat, together with a 'cat allowance' for feeding the cats. But, the rats showed no signs of decline in numbers. After a few days; the discovery was made that the cat allowance was misused by every one and the cats had become too weak to pounce upon the rats and catch them for eating.
