I am sorry I do not have insight to give you but I feel your pain. My Murphy boy acts like he is STARVING all the time too. He is exactly as your described your little one to be like.
Mia on the other hand is not like that so I have no idea if Murphy is not getting enough or what but I think he is just a little PIG - LOL!!
I think Murphy is starting to get overweight so I have been trying to be careful and only give him his 1/4 cup of food in the am and pm and thats it.
