Ernest Hemingway adored cats and had more than 30 of them in his migrations through Europe, the Caribbean and the United States. He felt that ‘one cat leads to another’ and called them ‘purr factories’ and ‘love sponges’. Among them was his beloved polydactylic cat (that is, a cat with extra toes on its feet). Cats figured in some of his most renowned works, including Islands in the Stream and A Moveable Feast. His cats even have their own biographer. You can meet them all in ‘Hemingway’s Cats’ by Carla Fredericka Brennen (ISBN 1561644897).
