Funny thing about cats is they know where they live. Until you move. And then, they know where they used to live.
This actually happened first and most strongly with Kylie, but all the cats have run back to the door of our old apartment on our new floor at least once, including Angel (and of course, before we actually moved, Jacoby actually went into that apartment); I used Angel in this cartoon mainly because the way she runs is so funny I thought it would be a lot of fun to draw.
