One time a small male cat showed up at my dad's doorstep, walked right in and made himself at home. Fortunately, the cat had a collar and tag. He belonged to someone who lived half a mile away! Outdoor cats do tend to roam, but neutered males don't usually wander that far. I imagined the cat traversing the neighborhood, going from backyard to backyard and chatting with old kitty friends like Burt Lancaster in The Swimmer.
