Cats don't like storms

We just had an incredible thunder/rain/hailstorm in the Boston area. I was home with the five cats, who were not at all happy about the situation. They ran around looking disconcerted, and the only thing that calmed them down was some lunch. Unfortunately, Duncan made for the hills (or the upstairs) before I could get any food to him. I haven't found him yet; clearly thunder and lightning are not his thing.
