Beast fable

 Beast Fable  is a short narrative, in prose or verse, that exemplifies an abstract moral thesis or principle of human behavior; usually, at its conclusion, either the narrator or one of the characters states the moral in the form of an epigram.

In beast fables animal characters are represented as acting with human feelings and motives. ... Among the best-known examples in Western literature are those attributed to the legendary Greek author Aesop. The best-known Asian collection of beast fables is the Pañca-tantra of India.

Examples: 

1}  Animal Farm by George Orwell can be classified as a fable. It features an array of animals who symbolize various classes of citizens and characters during the Russian Revolution. We learn that greed can blunder a revolution and undermine the people's determination to overthrow a corrupt regime. The animals are very literal depictions of real people. For example, Napoleon the pig is representative of Joseph Stalin.

2}  The Ant and the Grasshopper

In this fable, sometimes titled The Grasshopper and the Ant(s), the ant saves food for the winter and the grasshopper does not. When winter comes, the hungry grasshopper begs for food, but the ant refuses to share. The moral is, "Prepare for the days of necessity."

3} Gulliver's Travels is another modern-day fable that focuses on corrupt politicians. In it, Gulliver travels to four different destinations. First, he goes to Lilliput where he's large and everyone else is small. Then, he travels to Brobdingnah, where he is small and the locals are large.

Next, he moves on to Glubdugdribb where he's able to commune with the dead and understand all the deceptions that exist in history and modern day society. Finally, he travels to Houyhnhnms, where the horses are gifted with reason and the more primitive creatures look like humans.

Gulliver loves Houyhnhnms so much that he never wants to leave. It's a utopian society where wisdom abounds. By the time he makes it back to his home country - England - he's appalled by his everyday men. The theme here is that the world needs to be more moral and virtuous.
