I'm asking because mine is hungry ALL the time. He's a rescue and was very overweight when he came to me. He's obviously been fed a lot of junk in his life - he'll eat anything. I've managed to get his weight down to where it should be, but he never stops nagging for food. I give him a pouch of Felix every morning and another every evening, exactly 12 hours apart, and a small handful of kibble in the evening. More and he starts to put on weight again. He's about 7 years old, neutered. It's going to sound ridiculous but he pesters me for food to the point where I have to shut him out of the room. Any suggestions?
