We have tons of glass ornaments, mostly vintage. Luckily, we haven't had a tree climber in quite some time. However, I do tie the tree so it can't be knocked over. I have 2 hooks (one in the woodwork and one in a piece of furniture) about 42" off the ground that the tree is secured to. It used to get knocked over every time I left the house.
My cats rarely break an ornament; of course, the better ones are near the top of the tree.
