Tentatively named Banshee, since she is very talkative and wails anytime I'm out of sight. It fits with the theme of supernatural names for the other two cats (Spirit and Spook). Also I hope that she will be the omen of death to the field mice.
I wanted video of her talking, to demonstrate how she earned her name. However, she was silent and uncooperative for as long as the camera was out. Typical cat.
