Christmas Tree Shenanigans

We put our tree up Saturday.  Maybe it's a little early to some, but not to all, and since it's artificial, why not get it up now and enjoy it for as long as possible, right?  We are also experimenting with giving Spike and Shelby free (almost) reign of the house.  They aren't doing too badly, aside from being overstimulated.  Also, they have a fondness for climbing the tree.  At first it was just the bottom half or so, but as the day progresses, they are climbing higher and higher.  See the picture below of Shelby almost to the top.
