A philosopher once assured me, many years ago, that he had converted his cat to veganism. Believing he was joking, I asked how he had achieved this feat. Had he supplied the cat with mouse-flavoured vegan food? Had he presented his cat with other cats, already practising veganism, as feline role models? Or had he argued with the cat and convinced it that eating meat is wrong? My interlocutor wasn’t amused, and I realised that he really believed the cat had opted for a meat-free diet. So I ended our exchange with a simple question: did the cat go out? It did, he told me. That solved the mystery. Plainly, the cat was supplementing its diet by covert hunting. If it ever brought home any of the carcasses – a practice to which ethically undeveloped cats are sadly prone – the virtuous philosopher had managed not to notice them.
It is not hard to imagine how the cat on the receiving end of this experiment in moral education must have viewed its human teacher. Perplexity at the absurdity of his behaviour would soon have been followed by contemptuous indifference. Seldom doing anything unless it serves a definite purpose or gives immediate satisfaction, cats are arch-realists. Faced with human folly, they simply go their own way.
