Just be sure all decorations are unbreakable and nothing you put on there in harmful to cats!! See Kristens page on that http://67.15.70.205/talk/showthread.php?t=93238 I had one BIG girl long ago that I had to tie the tree to the wall to make sure she didn't turn it over climbing it.

Try to remember how inviting a tree is to cats and not get mad when they won't leave it alone! I have stuffed small mice and yarn cats I put on my tree when I put one up so my tree is always decorated for my babies... I never put anything breakable on mine. Haven't for many years... I have always had cats!
