My advice? NEVER feed your cat first thing in the morning or she will start waking you up REALLY early! Wait until you've been up for a couple of hours at least.
You can retrain a cat for this. I successfully retrained our cats from waking me up when I wanted to sleep in. Occasionally you can be the boss of a cat. Occasionally.
Karen, remember this simple rule. Dogs think of you as family, Cats think of you as staff.
