We had a cat once do the icecycle thing too. From then on we did not have them on the trees. Another thing the first Christmas we had Misty she ate a light bulb from the string of lights that was on the tree. It came right through and was in tact & did no harm to her we were lucky. Just the first year she bothered the tree but since then she just lays belly up under the tree looking at the lights in a trans it seems like.
