Does your cat mess with your Christmas tree?

Our cats are 13 and 14. Overall they are pretty lazy now that they are older. Up until a few years ago, they would still try to climb the tree when I first put it up. It was getting kind of scary those last few years, because the one cat is not exactly thin and the tree would teeter. I thought for sure she would make it fall over at some point. As much as they drove me nuts when they did that, I kind of miss their playfulness. I had forgotten about this until my daughter called me and told me her new kitten was trying to climb the tree all the time and she wondered what she could do about it. I told her to use the spray bottle, which did work. Anyone have any funny stories about your cat climbing your Christmas tree?
