Yoruichi in cat form wasn't much different from a regular black cat, but you thought that you could tell her apart from a normal cat...

... That was until one day, Yoruichi wasn't home and "she" arrived, but didn't answer you for anything.

You got angry with "Yoruichi" and started scolding her, until you heard a voice from the window.

"... Hm...? 'Cheating' on me with some stray cat?" It was clearly Yoruichi's voice coming from the window, despite her still being in cat form and almost unrecognizable.
