I am pleased to advise that Gus and Beans are enjoying their new furever home very much. I've had a couple of follow up chats with their new mom in the past few weeks, who reports that they are settling in well and are absolutely fascinated watching the squirrels and birds outside the windows (sights that were quite limited from my lofty apartment viewpoint). I am missing them a lot but I am thrilled that they have found somewhere so wonderful to live.
Of course, when they left, there was a vacancy in this chair.
But not for long.
