No, they've never touched them. I leave the bag I'm using out on that dresser and they've never been interested in that either. I haven't put a Christmas tree up around them yet! Looking outside is their favorite past time, lots of animals and birds around here.That's amazing that they aren't interested. My kitty loved sparkly and dangly things. He would steal my jewelry and take it under the bed to play with and he wouldn't leave the Christmas tree ornaments alone no matter how many times I chased him away.
