Cat volume computation

How do you compute the volume of a cat? Dunking it in water doesn't work-- you get the volume of the rat-like creature that lives inside the cat; much like the feeble alien within a Dalek. (And, if your answer had anything to do with contour integrals, get real.) Here is a method that works: Using successive approximation, determine the smallest box that the cat will fully enclose itself in. This cat is approximately 648 cubic inches in volume.
