Well, yes, I agree, it's good as a warning to get her onto the laminate right on time from where it's easier to clean...

But I don't think she's too greedy with her breakfast. She's only getting small portions, so she cannot eat too much at once. I think it happens when she eats bugs (the other day, I saw her eating a hoverfly before breakfast, and then she threw up); I always had the impression that bugs are making her sick.
