Hi Veronica! I washed my fleece 60°C only the first time, now I wash it with other laundry with a normal program 40°C, but without any softener Only today I ahve found a cheap bag which should keep the hair far from the washing machine and the other landry. So far I have washed the fleece without any bag but now I need to clean uo the filtre.
As for the absorbent layer there are different solutions: I use a simple piece of fleece fabric put on a layer of papers (leaflets from supermarkets). Once a day, during floor time, I remove the fleece, I shake it on the floor and I remove also the wet papers. Then I put new leaflets (you can use newspapers with you don't get tons of leaflets like me) and the fleece which had been hung out to dry. It is a practical method and I have no cost and no smell at all in the living room where the cage is. Of course you can also sew an absorbent layer with the fleece itself, but you need to wash it more often (maybe... I wash mine once a week) and it needs more time for being dry.
The pre-wash depends on the fleece and its quality; sometimes you need to wash it multiple times, sometimes only one time.
This is my cage... a very simple one, but the bedding works amazingly (with no cost at all... and my neighbours thank me for removing all the supermarkets leaflets from the communal mail box

)
