Does Your Cat Know The Sound Of Treats?

My cats go insane as soon as they hear a noise resembling food or treats being opened. They're so spoiled too. It's gotten to a point where I feel it's necessary to give them treats when they run over to me thinking they're about to get fed, while in reality it's just me making myself some food. My older cat though is very oversized. She's basically like a dog when it comes to begging for food at the table.
