Let's face it.  You're already low enough on the dominance scale at Poppy's house without having to be pushed around by a moody cat.

    You reprise your swan-kick pose at the top of the stairs.

    "Junior," you say.  "It's time to learn who's boss around here."

    You swing your foot up at Junior forcefully, yet gracefully.

    Junior is sent flying down the stairwell.

    Victory is yours.
 

    Celebrate!  Go bonk Sandy.

    Go back to the door to Sarah's room and make animal noises.

    Take Junior's place on the banister.
