"Caa. Foooo~." - Said while pointing to a can of cat food as we were dispensing some for the cat.

"Waaay!" Said with some urgency, on more than one occasion, after it becomes known that a food container of some sort is empty. (Indicating that we should throw/put it away.)

"Do you want a bowl for your blueberries?"
"Bow. Beeee."
