I haven't been able to have a tree since I got Andy in 1996. He just won't leave the things on it alone! The first year we had him I kept moving the ornaments higher and higher til finally by Christmas day the whole lower half was empty! Last year I got a tiny fiber optic tree for the top of a table. Of course there was a crash one night and a streak of white hightailed it through the cat flap and down to the basement! I did put up an evergreen garland over my archway between the living room and dining room and I have lights around that. The cats both look at it from the floor and can't do a thing about it!
