Pandora's perspective is one in which a girl turning into a catgirl and nobody noticing was a perfectly predictable outcome that she totally saw coming.

Granted, she did give Catalina that spell, so I guess it's understandable that she at least some of this coming.

What I love about this is that some readers didn't notice what had happened in the previous comic at first, either. It's actually entirely possible that someone will have reached the fourth panel of this comic and only then realized what was up.

I know this because, well, people told me they didn't notice it at first, AND because this has happened with transformations in the comic before. I think there's something about panel to panel transitions that can make change blindness applicable. Were the transformations animated, I think you'd have to cut away from a character and back to them with the change having happened inbetween for it to work.
