We have two ten-month-old kittens, if even that old. The tree went up, the ornaments came down, repeatedly. We just stick to ornaments that are safe around kittens. They don't have all that much interest anymore, they've got far too many toys to play with besides the tree plus a jungle gym of boxes and baskets. We've gotten pretty elaborate with setting up things for them to play with ever since Smokey got his neck wrapped around a speaker cord and almost hung himself one night. They're learning what's set up for them and what they aren't supposed to play with.

I did see in a magazine a tree that had the branches cut the first couple of feet and a smaller triangle of branches on the top half. It was like a topiary christmas tree. It'd be a good idea for keeping everything off ground level.
