Why do my family's Gatti seem to only meow to me when they're hungry?

If their bowl is empty and they're hungry when I wake up usually a couple of them will immediatly run over and meow to me. The thing is that I tend to wake up either last o successivo to last so usually there's already someone up that would feed them if they told the person they were hungry. And when they come meow to me I ask if they meowed to whoever was up and the person says no. Do they only meow to me because I feed them the most often and they know that if they meow and their bowl is empty that I'll feed them?
