I saw a cat on a barge once: I believe the barge was bound for Holland, but I have no idea where the cat was heading. Cats are thoroughly unpredictable in their movements. They do not signal their intentions as we do, or begin journeys in a predictable way. A cat will often deliberately look in the opposite direction to the one in which it is heading, and might scamper backwards as a prelude to running forwards (or jump onto something, only then to descend and wander off keeping low to the ground). So no, they do not navigate as we do. ‘CATNAV’ would be good for a spy trying to throw off a tail, but bad for finding your way anywhere useful.
