Recently, I was enjoying a quiet evening in my living room with the windows open. The kitties were each hanging out in a window, sniffing at the fresh air. I was engrossed in something on the computer when I suddenly heard a loud THUNK of cat against glass and a wail from Scarlett. I turned around and discovered that the orange neighbor cat was at the window! Neighbor cats usually visit at the more secluded bedroom windows, so I was very surprised to see the orange kitty. My surprise lasted about .2 seconds, and then I lunged across the living room to shut the windows. Scarlett was Not Pleased to have the windows closed and continued to hurl herself at the glass. On the other side, the orange cat paced around and glared at Scarlett. Melly stood by and squeaked.
Strangely enough, another cat came to visit the living room window the next day: a small gray one with the same huge amber eyes as the orange cat. I'd never seen the gray cat before, and I haven't seen him since.
