Anyone else got a kitty who's obsessed with human food?

I just caught Puff on top of the fridge chowing down on a package of saltines that she had ripped open---supposedly ancient and decrepit and yet she still manages to get on the fridge to get at human food.

There is nothing this cat won't eat. Her favorite thing is pasta in white sauce! She's stolen bacon off my plate; tries to bite the other end of sandwiches as I'm eating them; bats at me incessantly with increasing claw action until I share whatever I'm having with her. I often eat in front of the computer lately cuz this is the only room in the house the cats aren't allowed in!
