An extra-toes cat isn't a breed but any cat born with polydactyly, a harmless genetic variation that adds toes to one or more paws. A typical cat has 18 toes, while polydactyls often have six or seven on a front paw, sometimes forming a mitten-like thumb. The trait is dominant, so one affected parent can pass it to roughly half of a litter.
The Hemingway nickname comes from Ernest Hemingway, who was given a six-toed cat named Snow White. Most extra-toed cats in shelters are domestic shorthairs or longhairs, and their personalities are as varied as any cat's. The main care difference is claw trimming, since extra claws can curl into the paw pads. In Parkersburg, that routine fits easily into an indoor home.
