I stopped using the glass ornaments on my tree a few years ago. My cats usually were not the ones who broke them, though. They would just knock them off the tree where they safely landed on the carpet, then the ornaments would roll under my rocker/recliner and when I would sit in the chair, it would rock forward. I would hear a crunch and that was the end of another ornament. And sometimes I could almost swear my cats were laughing at me.
