My cat fell of the window from the second floor today. With the current heat, the window in the front is open and she would sit and walk on the windowsill now and then. She was sitting there, when I accidentally banged on the window, which must have startled her. Next thing I knew, she wasn't on the windowsill anymore but down on the ground. By the time I got outside she had already entered next door's building trying to get somewhere inside. I carried her back home, somewhat startled by her little adventure (she's an indoor-only cat). She seems okay, but is limping slightly, so I'll have to keep an eye on her the following days. At least it's not broken. I don't think she'd be walking on it or jumping if it was.
