What can I safely spray on indoor plants to keep cats away?

Our question this week was:

Is there anything I can spray on my indoor plants that will not harm the cats or the plants? I have tried growing special “cat grass” for them, but they seem to enjoy my plants more. None of the plants are toxic but they get quite ugly from the grazing. I have had suggestions such as insecticidal soap or a hot pepper spray, but I would like a professional opinion.
