So we asked her a couple times, 'Potty?!' and she happily pranced to the door but upon opening the door to the backyard, Shadow saw the fence and became confused.
Hour 12. Still no poop.
Sounds like you broke her comfort zone with the bathroom.
We did the same thing when we erected a wire shelf above the litter box, the cats were all freaked to go, then they started lying in the box before they realized "oh hey it's the bathroom" and used it for that instead.
Here's to functional poo!
