The company Argos has come up with a "half Christmas tree" that will keep the cat and kids from swatting at the ornaments while providing extra room for even more presents.
The parasol tree is 6 feet tall and is a pretty inexpensive purchase. You can also get a "snow covered" version of the tree that's slightly more expensive. Here's the link.
If cousin Eddie from Christmas Vacation could talk now he'd say, "Sure is a beaut' Clark, ain't he?!"
