So, thanks to Janice having heard good things about it, we watched the documentary THE LION IN YOUR LIVING ROOM, which I highly recommend.
Midway through it, Feanor got down from Janice's lap, walked halfway across the room, and sat himself down to watch what was going on. I think he was listening more than watching, attracted by a section in which they played a variety of different cat vocalizations; Janice thinks he was mainly looking. In any case, it definitely attracted his attention (usually it's Hastur who watches the tv at odd moments, but she was in another room at the time).
By the way, that's my Sime in the background to the upper left; to the right of it are Janice's two Naismiths.
