Step 1 : Introduction to the question "Roughly half of the cats living at the Ernest Hemingway Home and Museum share what distinctive physical trait?"

...The Ernest Hemingway Home and Museum in Key West has become almost as famous for its cats as for its connection to the writer. The property is home to a colony of polydactyl cats—felines born with extra toes, often six or more on a paw. The tradition began when a sea captain gifted Hemingway a white, six-toed cat named Snow White in the 1930s. Hemingway adored the trait and allowed Snow White’s descendants to roam his home. Today, roughly half of the 50–60 cats on the property carry the polydactyl gene, giving them their distinctive paws.
