The odd thing about this was that the cat seemed quite unaffected. This is not to suggest that he had learnt to live with his sad affliction, or that he was courageously making the best of things. He was, quite simply, unaffected. He didn’t seem to notice. Not content with ignoring the normal requirements of biology, the cat was also in clear breach of the laws of physics. He moved, jumped, promenaded, sat, in exactly the same way as if his rear half were present.
