Nommability is the state of being nommable. Nommability is measured not only by the freshness, texture and flavor of the food item in question, but also by the attractiveness of the presentation. Today's breakfast, for example, scored a 9.5 on the freshness/texture/flavor scale, but only a 5 on the presentation scale (although the tray was clean, it was conspicuously missing its brightly-colored placemat, which remains in the Human's laundry basket, unwashed, for the second week in a row). Thus, the overall nommability rating of breakfast today was 7.25, bringing it just barely into the "Acceptable" category.
You gotta do better than this, Human.
