As noted, the boys' buffet was open all night. I refreshed it with Emily's kibble when I did a new bowl for her this morning, meaning they now get 90% Active Maturity kibble. (In other words, when they finish the kitten kibble still left in their bowls, it's gone forever.)
One new breakfast detail is that I left Emily's dish down in her suite when I opened the door after she had eaten. Of course, the boys had to charge in and raid her bowl. Never mind it's the same kibble we now feed them, like any young male they think the food tastes better in the girls' cafeteria.
(There is plenty left for all concerned.)
