Explanation:
George Orwell's "Animal Farm" is an allegorical novel about the animal species protesting about their human masters. They are seen fighting for their freedom from the humans. They want a society where they can take care of their own affairs and not involve the humans in their lives.
When the humans began spreading the rumors about the animals practicing cannibalism and tortured one another with hot horseshoes, they were just trying to discredit them from further success. The animals had successfully lived their lives, maintained their society in perfect peace which the humans seem incapable of doing. This success of the animals made the humans envious of them. But instead of trying to follow in their ways, the humans decided to spread false rumors and try to discredit the animals from their successes.
