graylocks, try putting it somewhere away from the cats' reach but close enough to where you found it, that mom will be able to find it. That being said, the egg is likely not going to make it anyway-- if they aren't kept warm for a significant period of time, the cells die... don't feel too bad, things like this happen, you had no way to know the nest was there.
