I call this one "twin towers." This is a picture of Nimby(left) and Raven(right) when Raven was just introduced to Nimby. They still catfight. Raven came with the tower that Nimby is on.

It's nearly christmas, and Raven(a cat) is getting into trouble...again. She is playing with the ornaments by batting them with her paws and trying to chew on them. She's hyperactive.
