The cat pee quilt just wash and dry before shipping. Wash on medium warm and thumble dry normal heat or line dry. When you wash the quilt besure to add a Shout color catcher. I have front loader washing machines and have never had a problem only when I had top loaders that have agitators did I have damage to the quilt. So you might take the quilt to a laundry mat to use a front loader or ask a friend.
