I love the Simon's Cat series - the cat always pointing to his mouth for food. We had a friend who had a large ginger tom. He slept all day at home, had his meal, went out for the night, came home . had a meal. This was his usual routine. However, one time he didn't come home for several days. So posters were put up, with a phone number, all over the area. Eventually someone rang to say the lost cat sounded very like their ginger cat. Except the cat had been injured, broken a leg and was confined to the house. Long story short. It was our friend's cat he'd been living a 'double life' for several years. The 2nd owners though he was a stray. So once he left house A, with a full stomach, he went to house B for the night, being fed again and slept the night, breakfast and off to house A. The two owners decided to keep the cat's way of life only reducing his food intake as he was getting quite fat.
