What is the central idea of the article Dog, Cat and Mouse?

Dog, Cat and Mouse is triggered by attacking "gentlemen", mocking the "gossip" they spread, and expressing their hatred for cats' characteristics of "torturing the weak", "howling everywhere" and sometimes "coquetry". Recalling the experience and feelings of a lovely hidden mouse being rescued in childhood, it shows sympathy for the weak and hatred for the oppressor.

The reason for becoming an enemy is that dogs play tricks on cats.
