Can-Opener Cat

I've never had a cat that came running at the sound of a can opener. I do now.

All last week, as part of my diet, I had either canned tuna or chicken for lunch. I would pour a little of the water from the can into Molly's food bowl, and she loved it. But now, when she hears the can opener, she comes running, meowing and rubbing against my leg, begging for tuna or chicken. I try to tell her it's only green beans -- I even let her smell the can -- but I don't think she believes me. She looks a little betrayed, like I'm trying to keep all the tuna for myself.
