I developed a new game with Walter this morning.
Me: Pick up kitten, deposit into still-wet-from-shower tub.
Walter: Hop out! Stare up at Andrea, say, "Mrroww."
Me: Pick up kitten, deposit into still-wet-from shower tub.
Walter: Hop out. "Mrrrow!"
Me: Pick up kitten, deposit into still-wet-from-shower tub.
Walter: Hop out. "Mmmr. Row!"

And so on and so forth, for several more iterations, until bored. Really, what are kittens for, if not this?
