Hidden safely where the family can't see you, you giggle silently as you watch the family react to their sudden gender-reversals. (Not to mention their species-reversal!)
You think for abit and decide there's something missing from this family.
Ah ha! They need a pet!
You know just the way to mix things up even more. And so with a wave of your wand the mother calico (or former father) begins to shrink, losing her human characteristics until she devolves in a normal calico kitty. She meows confusedly, and the family, too shocked to know how to react, tries to comfort her.
The black tomcat (former eldest daughter) pick up the calico and tries to calm her down. But that doesn't last long, as he too shrinks into a regular cat.
You smile at the two cats as they nuzzle each other and wonder if they'll ever adjust enough to become a couple. Meanwhile the rest of the family backs away out of fear that they too will be fully transformed.
But you know that won't happen. As your finishing touches, you age the former son into a adult female cat morph. Voila! Now they have a new mother. You giggle and fly out the window imagining how they'll be able to adjust to their new lives. You'll be sure to check on them again in the near future.
But for now, you have more ideas for michief.
