I was reading this short fable by Kafka, and instantly thought of "The Metamorphosis". It is about a mouse who throughout his life, spent most of his days running around, admiring the size and vastness of the world around him. One day he realizes that the walls of great size are actually getting smaller, and therefore limits where he can run. The mouse soon runs into a corner and meets a Cat. This was his last encounter. Can we connect this to "The Metamorphosis" and how Gregor's job could be the walls growing smaller and smaller in his life and eventually leads to his final 'trap'?
