Did my cat learn her eating habits from me?

I realize that everyone and her cat has a weight loss blog out there. My cat could actually use one now that I think about it. She is even fatter than me. At least proportionally. She probably only needs to lose 7 pounds where I could stand to lose about 70. I like to chase her and watch her pannus sway to and fro (see "Pannus" blog). Is that wrong of me? At least we are both getting some exercise by running our fat asses around the house.
