Merry Christmas! I haven't put up a Christmas tree in years because one of my cats used to climb up into the branches. This year, I put up a cat-safe tree, which is an artificial tree without ornaments. It's also standing between two bookcases, so my current three cats cannot easily climb into its branches. I keep turning the lights on and may want to keep the tree up all year because I love it so much. Why should I hide something I love in the basement or attic?
