Tonight, Fred did something different. When I whipped the feather around the front of the chair, Fred "snuck" around the back of the chair, surprising the feather (and me) on the other side. She did the same thing a few times. Funny that she suddenly learned something new about the local geography.
Frederica, the senior cat in our household, loves to chase the feather dangling from a pole. If she feels it is time to play, she emits a very annoying yowl. One of the standard ploys is to dangle the feather between the chair (by the front window) and the cat table. Since the feather is "cornered", Fred lunges at it. I whip the feather around the front of the chair to the other side. Fred dashes around the chair, and the I whip the feather toward the center of the room. Of course, Fred continues to chase. This particular sequence has become so standard that Fred sometimes anticipates the last move. She doesn't go all the way around the chair but cuts toward the center of the room.
