My cat Indigo - the silent one - likes to explore and do acrobatics. I have seen her, more than once, hop from the top of a dresser to the top of an open closet door and balance there, on that narrow ledge, looking around for the next place to go. She is so funny riding the door back and forth as it wobbles under her weight. (She is a trim kitty, which is why she is able to get around so well - her plump sister Beauty would not have such luck, if she tried.)
