The cat, mice, the weasel

"The cat is called musio, mouse-catcher, because it is the enemy of mice. It is commonly called catus, cat, from captura, the act of catching. Others say it gets the name from capto, because it catches mice with its sharp eyes. For it has such piercing sight that it overcomes the dark of night with the gleam of light from its eyes. As a result, the Greek word catus means sharp, or cunning. "
