I called the clock repair place and will take it in next week. I will take a better look at the clock tonight, when I get home. After it is repaired I will use double sided carpet tape to keep it in place. I just can't figure out how they did it. Maybe it was both of the cats at the same time, wrestling. I will never know. I surely hate to confine them at night, but it may come down to it. I should have gotten up last night but I just didn't expect the noise to be coming from a precious item crashing but instead I figured they knocked a lamp over.

Cats!
