I have a vague childhood memory of my kitten running up the tree with airplane ears, ornaments flying all over the place. We had a glass star and she ran straight up to that and whacked it off and it broke. I found it quite entertaining though, it wasn't a disaster to me!

Not a pet, but Jaden was involved in a Christmas disaster once. He was about two years old, just beginning to walk around. It was my first year with a nice house, so I went all out on the Christmas Tree. It was tall with all sorts of beautiful ornaments. Well, I heard a crash and a muffled cry. I went out into the living room, and all I could see is his hands. He'd pulled the tree down on top of him. The tree water stained the carpets and the poor little guy was scared.
