My cat Pinkerton, out of sorts at having been intermittently fed by a neighbor while I was away, sat with his back to me, retaliating by refusing to let me pet him. Upstairs, the tenants who had moved into the floor previously occupied by Rafael and Mama G were throwing a noisy party. I turned up the volume of the telecom slightly and used my cyberear to filter out the worst of the laughter and music from upstairs. In response to the increased noise, Pinkerton leaped off the couch and disappeared through his cat door.
