When you have cats sometimes you can’t have Christmas trees. Baubles and tinsel are just too tempting. Cats who climb will be up to the top of the tree in seconds. There is also the danger of them chewing on the tree lights wire. Also you don’t know if they are going to chomp on some of the traditional toys, like tiny Teddy bears, that might have been handed down from generation to generation. Granny’s baby jesus or the angel with real feathers can be casualties! I’ve seen a few videos of anti cat tactics, and the one of hanging the tree from the ceiling looks pretty good. One solution I once did was to cut out the shape of a Christmas tree and container and stick it to a wall, then sticking real baubles and ones you have drawn onto it. Make sure any baubles are stuck on well and are anti shatter. Other ideas include a bauble free tree… But it might still get climbed!
