The prevailing Yen family belief is that of our two resident cats, Fatboy is the less smart. So when Kim bought a bed for the cats, and they decided that my backpack and other less comfortable things were better places to rest, we began to wonder which one of them was going to figure out that the bed was more comfortable than a bag with books and pens in it.
Since Helga had shown herself to be smarter, in general, than Mingus (aka Fatboy), we assumed she'd be the first to figure it out. We were wrong, as you can see. We thought that maybe, in the end, he's not as dumb as we thought.
But then again, maybe he's just lazier.
