We put in hardwood floor, which helped. As soon as Ancient Kitty cashes it in, we're gonna replace the rest of the carpet - lower level rooms and bedrooms. Ms. Ancient One may need some help in that regard, but it's so hard to choose the day to say "that's it." She has a special liking for my son's room, for some reason, and the poor kid is getting so upset about it. I can't blame him.
