Story time: We had a cat named Mowie that absolutely loved bread and pasta. If you gave her a bowl of plain pasta she would eat it voraciously, even growl if you got close to her while she ate. She could finish a small bowl off in a minute. I have never seen a cat take suck big bites either.
We had to get a bread box because she would tear open the tops of loaves and eat the crust. It was kind of annoying but also funny because she would be on a loaf as soon as you took it out of the grocery bag. All bread had to go immediately into the bread box. This is how I know Garfield was based on a real cat.
