Macavity at rest
For all his kittenish energy, Macavity has to sleep sometime. When he does, he looks like some kind of wind-up toy that's temporarily wound down, or a little steam engine that's run out of steam. One can imagine him mustering his strength for the next great assault, his neverending fight to make the house a little less boring, a little less drab.
But that aside: isn't he just cute as a button?
