Anyone who has ever had a cat at Christmas time, knows that trouble lurks.  Cats like trees, so the obvious happens when you bring a tree into the house!

Can you imagine the cat's delight, when you set up your Christmas tree?  A tree for me for Christmas...  aww, thanks...meowwwww!    Well there are a few things you can do to cat-proof your tree.  First, Put something like orange peels under the tree to make your cat less likely to go near it. (Cats also dislike the smell of rotten apples.)  Second, use duct tape!  If the tree is shorter than 6 feet, use duct tape to tape the legs of the holder to a piece of wide ply-wood and put the whole thing on a short, sturdy table. This keeps the tree above their level and the cats won't be as interested.  Use a piece of high test fishing line to connect to the top of the tree to the ceiling. This will prevent the tree from tipping if the cat does decide to go for it!
