I've been holding out on getting carpeted cat trees or any type of cat tower until I figure out where I want to put it. While my mom was at the goodwill she found a basic carpeted cat condo that was covered in cat hair. The fact that the item is second hand does not bother me. What's bothering me is that I don't know if there is kitty sickness on the thing. I guess what I'm asking is has anyone ever bought carpeted cat furniture second hand and if so how did u clean it before letting your loved one play on it?
