Ebony went to her final reward the day after Osama Bin Laden. I don't know whether that means anything but she was a way better cat than he was a human being.
Robin and Jeri both knew Ebony (Mama Kitty, Molly) well. Robin often babysat for her and the rest of the cats. Jeri shared an office with her, the rest of the cats, and Nancy and I. Besides Jeri's other office duties she usually fed Ebony (and the others). She often babysat for her, also.
The thing I'll remember most about Ebony was her beautiful, graceful walk. It was exactly like a model on the "catwalk". I think that must be where the name came from.
