I was glancing at your title and then thought to myself, well she'll be all right so long as they don't use a jack hammer. Lo and behold you will.
Years ago, we had a cat that was in the house when we had to jackhammer an opening for a bulkhead. According to my mother, the cat went absolutly crazy and she eventually had to have him put down.
I'd board the cats if possible on those days - they may be ticked at you for doing it but in the long run, they'll be better off.
