Glad you found her, I had a similar incident a few weeks back. One of my het pied girls escaped from my rack (one of my kids left her tub open just an inch or so and she squeezed out) and was under my son's bed. I saw our cat run like a bat out of hell out from under the bed and sure enough, there she was. She was striking at anything that moved so I was pretty sure the cat had been harrassing her pretty good. After covering her up, I was able to calm her down and get her back into her tub. Needless to say, I know exactly how you felt and it is not a good feeling.
