My parents had a very tall vaulted ceiling in the dining room of the house where I grew up. My father liked tall Christmas trees. The tallest we ever got was a little over 15’.
THAT is the tree one of the cats (a stout, black and white, ex-male 18 pounder) chose to climb to the top of, and to subsequently topple.
It was quite a mess. The cat, of course, came through the event unscathed; but there were a LOT of broken ornaments and light bulbs (we still ussed some relatively large-bulbed glass lights at the time).
