L. Frank Baum,
The Magic of Oz
“ The Cat was sour-tempered and grumpy, at first, but before they had journeyed far, the crystal creature had discovered a fine amusement. The long tails of the monkeys were constantly sticking through the bars of their cage, and when they did, the Glass Cat would slyly seize the tails in her paws and pull them. That made the monkeys scream, and their screams pleased the Glass Cat immensely. Trot and Dorothy tried to stop this naughty amusement, but when they were not looking the Cat would pull the tails again, and the creature was so sly and quick that the monkeys could seldom escape. ”
