Being easily domesticated, it is kept in many houses in Hindustan, to rid them of reptiles and other vermin, as rats, mice, etc. It has been said that it neutralizes the poison of snakes, which it fearlessly attacks, by eating, during its contests with them, the snake-root; but its immunity is really due to the extreme celerity of its movements. It is of a reddishgray color, and somewhat larger than a rat.
