The Vanity of the Rat is a satire story, Satire is primarily a literary genre or form, although in practice it can also be found in the graphic and performing arts. A common feature of satire is strong irony or sarcasm—”in satire, irony is militant”—but parody,  exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. This “militant” irony or sarcasm often professes to approve of (or at least accept as natural) the very things the satirist wishes to attack. It is also a way of making fun of  peoples defect and wrong doing.
