The Wolf in Sheep’s Clothing

A Wolf found great difficulty in getting at the sheep owing to the vigilance of the shepherd and his dogs. But one day it found the skin of a sheep that had been flayed
and thrown aside, so it put it on over its own pelt and strolled down among the sheep. The Lamb that belonged to the sheep, whose skin the Wolf was wearing, began to
follow the Wolf in the Sheep’s clothing; so, leading the Lamb a little apart, he soon made a meal off her, and for some time he succeeded in deceiving the sheep, and
enjoying hearty meals.

Appearances are deceptive.

The Fox & the Cat

A Fox was boasting to a Cat of its clever devices for escaping its enemies. ‘I have a whole bag of tricks,’ he said, ‘which contains a hundred ways of escaping my enemies.’

‘I have only one,’ said the Cat; ‘but I can generally manage with that.’ Just at that moment they heard the cry of a pack of hounds coming towards them, and the Cat immediately scampered up a tree and hid herself in the boughs. ‘This is my plan,’ said the Cat. ‘What are you going to do?’ The Fox thought first of one way, then of another, and while he was debating the hounds came nearer and nearer, and at last the Fox in his confusion was caught up by the hounds and soon killed by the huntsmen.

Miss Puss, who had been looking on, said:

‘Better one safe way than a hundred on which you cannot reckon.’
