It's Cleo, of course. Playing with this rug is one of Cleo's very favorite things. She is also very fond of boxes. The Mom found Cleo hanging around outside the house, looking very uncared-for and hungry. She invited her in and she has been a member of the family ever since. Cleo is the adventurous one and was the one who was most likely to jump over the fence at the old house when they had a back yard to play in. Cleo could be very bad at not coming in when she was called. It got to the point where the Mom would bring Cleo in while the other kitties played outside, because she just wouldn't mind. Other than that, Cleo is very well behaved and gets along well with Casper and not quite so well with Patches. Lately, though, Cleo and Patches have been seen sharing a sunspot or a nap spot, though not touching each other.
