This is so funny.

One year we tried tying the fake tree top to a plant hanger. We had one cat who loved to climb the tree and knock it over. That worked out for about half an hour, until the bottom half of the tree separated from the top half via a cat climbing the tree. The rest of the time the cats would lay under the tree as soon as it was set up. We usually don't put it up until the last minute. Sometimes we don't put it up at all. Presents go under the tree on Xmas morning, otherwise cats and dogs would rip them to shreds. Sometimes we put up a small one in our bay window. They always knock it down.
Two or three years ago, we bought a new "fake" tree, a really nice one, pre-lit, etc., etc. Boy, it looked nice. (I don't buy real trees) So, after the holidays, DH decided he would donate it to a charity thrift shop along with some other items we had that were pretty new, rarely used. To make a long story short, he accidentally donated the brand new tree instead. He insisted he didn't do that, and we've scoured the house stem to stern many times. No new tree. I wondered if it was a dream, but I have photos of it. LOL
OT, but we still using the "old" Charley Brown Xmas tree.
