I'm sitting on the porch, serenely watching the animals play in the yard. Suddenly, Prodigy trots up to the porch, walks past me, and goes inside. After a moment, I get up to follow him, to see why he's inside. He's just finishing up in the litter box, and now he's hurrying back outside to play some more.

I tried telling him that coming inside to use the litter box is like getting out of the ocean to pee, but he didn't really follow.
