In this Aesop's fable, a cat fell in love with a young man, who in turn thought of her as, well, a cat. So she asked Venus for help. Being a good sport, and also the goddess of love and beauty, Venus turned the cat into a fair maiden. The young man was immediately smitten and wanted to marry her before she could even set up a Match profile. Upon further reflection, Venus began to wonder if the cat's nature had changed, or just its appearance. To find out--and because gods and goddesses were always messing with the poor, dumb humans--Venus let a mouse loose at the couple's wedding. (I'm pretty sure etiquette experts frown on this sort of thing.) The cat-maiden pounced on it, which grossed her new husband out to no end. Having found her answer, Venus turned the young woman back into a cat. The moral of this story being, true nature always wins out.
