Ernest Hemingway's home in Key West still keeps house for dozens of six-toed cats. They are descendants of a single polydactyl kitten a sea captain named Stanley Dexter gave him decades ago. Sailors considered the extra toes lucky and good for mousing, which may explain why Hemingway kept collecting them.

The house predates its famous tenant by eighty years, built in 1851 by a shipping magnate whose fort-like design and high perch let it shrug off Key West's fiercest storms. Pauline Hemingway's uncle bought it for the couple as a belated wedding gift in 1931. It was here Hemingway wrote A Farewell to Arms, To Have and Have Not, and The Snows of Kilimanjaro.

VoiceMap's self-guided audio tours use the house to anchor Key West's improbable literary colony, tracing how John Dos Passos first talked Hemingway into visiting, and how Robert Frost and Tennessee Williams later followed him to the island.
