It was 2 AM and there was not one but two intruders.
Better know as bats, most likely the the Little Brown Bat. Luckly for them Sans-souci could not catch them, not for lack of noisy trying. So I "netted" them with a sheet and rolled them out on the balcony. I accidentally chased one into the computer room so it was real fun netting it while trying not to knock anything over in the precess. It's been a while since we had bats in our place.
