Well, the cats knocked down the Christmas tree. It was in the morning, before we'd gotten up, and we heard a loud thump from downstairs. The tree hadn't been decorated yet, luckily, so no damage done (to tree or cats).

We decorated it last night, and it was still up when we left this morning. We can only hope it's still up when we get home tonight. Knock on wood. Q*Bert was meowing a lot this morning though...maybe he was trying to tell us something. Like "Don't leave or we're gonna take down the tree."
