YouTuber Rina Takei has documented over the course of the past 8 months, how her black cat named Guinness has reacted to the window washers who come to clean on a fairly regular basis at her high-rise building. In February of 2015, Guinness was curious about the man dangling in front of the window. In April, the window-washer tried to engage with Guinness, who just took it all in. In July, the curious kitty grew even curiouser. Finally, within the past week, Guinness began to adorably interact with the smiling window washers, even as they came from the side. In fact, Guinness seemed to miss them when they went on to the lower floors.
