"Where you go when you're a naughty kitty who suffered the squirt bottle one too many times."

Look, it's the first metaphor that comes to mind. So sue him. Or maybe don't, he's pretty much broke here. He can already tell that any world with a talking cat had some radical differences from his own, so best to break a complicated concept down into bite-sized pieces.

Speaking of biting... damn, son. Better not mess with those teeth.

"Nice jawline. Very solid. You're not gonna nibble on me next, right?"

Not that he's worried or anything. Just checking.
