Do check.
Just this morning Mrs.L asked me to replace a bad light bulb (which I had replaced only a month ago) and it turned out that evidently the poochies had somehow managed to unplug the device sometime last night.
That, or we have ghosts of some sort - it's not the first time this has happened to this particular lamp.
The cats have knocked plugs out behind the entertainment center before. Hubby got all worried that the DVD player wouldn't work awhile ago, and I told him to check the plugs before he had a coronary. Yep. It was loose. The cats are behind there all of the time, and knocked something loose.
