This creature has taken up residence on the sofa amongst the sofa pillows. It has, apparently, been taunting its real-life counterpart, Vader Kitteh. I didn't witness it personally, but there very well may have been what my grand dad used to call a "set to" between the creature and Vader Kitteh because the other morning the creature was found laying down on the floor (too small to jump back up on the sofa by itself, no doubt) and Vader wasn't talking. Further news as it breaks.
