When Snowball first came to live here we watched in horror as he jumped on top of the flatscreen in the living room and balanced there. Us humans froze, thinking "sudden movements might scare him and make him either scratch the screen or catapult off of it leaving it in pieces on the floor!" One of us finally managed to creep over to rescue him. Later we realized that the base is heavy and sturdy enough that a cat couldn't easily knock it over.... I guess I am more surprised that no other resident cat had tried doing that before!
