Pretty darn close I think. Yesterday's poop was massive and had quite alot of chunks. I'm expecting a few pieces to show up over the next day or two before she is totally cleared out, but id really say we are pretty close to the total.The extra soak will never hurt.
Start cutting the cucumber back ~ 1/4 inch a day. The romaine is fine.
I'm really doubting she swallowed anything larger than bite-sized, so by the time you get the cucumber eliminated, it should be fine to return to As Usual routines.
I'm guessing you've estimated about the *right* amount of the missing chunks?
