Use lino rather than fleece - you can buy a short length from any DIY store and it's usually anti-bacterial - this is much easier to keep clean as it won't get sodden with urine and can be wiped down daily. You can cable-tie it onto the shelf if your ratties try and pull it up.
fleece will get smelly really fast so vicki and kevs idea is a good one
