In the not so distant past, I acquired another cat (read about him here and here). In the not so distant future, I will be buying a new TV.
From clues left behind by the purrpetrator, it appears Beau knocked the sound bar off the TV stand, and the sound bar hit the screen, damaging the display at point of contact. I would be more upset, but the display on this TV has been problematic for a while, so now I have an excuse to buy a new TV. And lock Beau out of the den.
