An old mouse chanced to see a cat wearing a few beads round her neck.
"Ah," said the mouse with joy, "that cat has turned vegetarian."
Thereupon, he brought his offspring along to pay a call on the cat to express
their gratitude. No sooner had they appeared than the cat gave a deep howl and
devoured several mice in rapid succession. The old mouse turned tail in the nick
of time and made good his escape. 
Sticking out his tongue, he cried: "My, my! That pussy is even more ferocious after turning vegetarian."
