I have used Rescue Remedy on my cats before. It is super mild though. It sounds like you need a mild tranq for her. I had a dog that used to freak out over fireworks really bad. He chewwed through a picnic table one time. We had to knock him out after that. Your doc will be able to advise. You could try the Rescue Remedy and see though. I know from personal use that it is super mild. But it might work for her and is not as druggy as a tranq can be.
Blessed are the flexible, for they shall not be bent out of shape.
