I switched to fleece last week mainly because the boys popcorn so much round their cage that they were throwing out so much bedding all over the floor, and because my Teddy Girls have sensitive skin.
I have commercially made Ferplast style cages. I have a bottom layer of several sheets of newspaper, then a towel, then a layer of a type of washable (flat) nappy called Prefolds or the traditional Terry towelling squares. This is just because I had them left over from my children! Then a layer of fleece on top.
For me (so far) its worked well. I actually am changing the cloth fleece and cloth nappies on the top of the towel every other day and the towel if its soaked through the cloth nappy.
ere aren't loops on the nappies they can catch their feet on are there'
