A woman was troubled by mice.They ran inside her house at night.In the day,they were in hiding.
The woman thought,"What I need is a good cat,a good mouser." She knew of a man who had cats for sale.So she went to see him."Do you have a cat that's good for the mice?" she asked the man."Well,yes,I do happen to have a cat that's good for the mice," replied the man."I'll take it," said the woman.She paid for the cat and took it home.
