Jimmy's the kind of guy that is always on the move. Everything is so exciting, so he's always UP! As a result his little internal engine is perpetually running hot. This causes him to seek the coolest places the house has to offer, like the a/c vent, the basement (but only if we go down with him as he is no loner), or in this case, the tile floor in the bathroom. He even goes so far as to scrunch up the rug to make sure more of his body is in contact with the cooling surface. It has the pleasant side effect of creating a little headrest for him. He's done this on multiple occasions, so this is no accident. He paws and wiggles 'til everything is to his liking.
