For fleece, as long as you follow the guidelines on the "Fleece Project-study" sticky. It doesn't smell at all. It will if you miss a day of vaccuming up some poops, so you have to be on top of that. Also, for a nice clean smell wash them in vinager instead of regular detergent.

Edit:: Also, it's very hard, and from what I hear on the site it's a good 50/50 chance you're pigs will never be litter trained unless you are very.. VERY Adament about it. My piggers arent litter trained.. and like I said, if you are doing what needs to be done on the fleece, it wont smell either way.
