I have the same problem. Angel is always looking for food. It breaks my heart when I put his kibble in a bowl, it looks like such a small amount! But, he will not become obese! For me, that's worse than seeing his meager amount of food in the bowl! He gets the proper amount, plus he gets a treat here and there.
I feed him at around 7:30 am and 6:30 pm, with a treat in between.
