16 pounds is big, but it depends on what kind of a cat. For a Siamese that would be unusually huge, but for a Maine Coon that is abvout average. Scoots and Max are both around that. I have no idea what Simon weighf. I would guess about 10-12 pounds, that is about right for a male Siamese. The photo is a lynx, Simon is a lynx point. A tiny wild cat! .
