I had a cat named Snowball that climbed the Christmas tree without fail every year - until she knocked it down and scared herself so much that she quit. After that she contented herself with just sleeping under it and we used to tell our then 3 year old son that she was waiting for Santa to come. She passed away a few years ago and I still think about her when I set up the tree. The cats that I have now don't bother with it, which is a blessing because it's no fun fixing a tree after a cat destroys it. My current cat Mittens used to like eating the tinsel, which is never good because they have to digest what they eat. You should never try to pull these out by the way because it can damage their intestines. Just use scissors to cut them off. I know - yuck - but it does happen and it needs to be said. The safest practice is to not use tinsel if your pets like to eat that stuff.
