The inspection didn't go well.
As the previous photos show, there is a pony wall between the tub and the shower. This now has ~ 3 feet of glass on top of it, similar to before the remodel. What's not similar is the glass is offset towards the tub to make the shower side a usable shelf. Katherine specifically approved this, but she didn't copy the cats on the approval.
Oscar, Penwiper, and Whitey each tried to jump up from the lip of the tub to the pony wall expecting the former narrow but usable landing area, and instead smacked into the glass and fell back down. Whoops! No one was injuried.
Billy, being the brilliant leader of our crew, didn't try it. Instead, I later saw him tentatively put his forepaws up on the pony wall to inspect the the glass, rear paws firmly on the tub.
No one has tried for the shelf since, so apparently the lesson was quickly learned
