My cats are smart. Aren’t they all? They know when we are headed out. In fact, Patch is positively frantic when the suitcase comes out of the closet. I’m told that dogs (maybe cats?) have no sense of time. They sure know when something is about to happen. I whistle and they come to the door in order to go out on the deck. Everyone was gathered. Maybe it was coincidental? I think not. Yes. We miss them when we travel. And they miss us.
