So I was sitting here peacefully at my computer, and eris_raven was perched on the windowsill, when suddenly:

BANG!
SKREEEK!

...a thump and the polyphonic screech of fingernails on glass at the window. eris_raven crashed out through the blinds, then poked her head back up to see what was going on.

I raised the blinds to see what was going on. Nothing, evidently. I went around to the living room, and saw the fluffy dark cat (black with rusty splotches) who's been hanging around, and evidently is cared for by the Yelly Lady or the caretakers or both. I chivvied Eris into the room, and then slightly regretted it -- we got a full-on cat fight through the glass. There was yowling, and hissing, and I got to see my cat's tail triple in size. Eventually, she slunk off, ears back, growling.
