Btu, we all know that.

During their rare appearances for other than food or a toilet break, cats often go mildly beserk. With flattened ears and tail at a jaunty angle, they go tearing around the house doing the most spectacular but inane things imaginable.

Then, for no reason, they will suddenly sit, lick a paw, and walk out in the most stately manner known to the animal kingdom.

Thus, we who live with them, are continually amazed and endlessly entertained.

Silly Cat! ;-}
