Just to say have used profleece for 1 day and night with 2 babies in a Nero 3,loved the way all the poos and hay came off easily into a dustbin bag,I sprayed the wee area{all up 1 corner},and let it dry out on the line ,I then lined the cage with newspaper and put the fleece back in.The piggies love it and are sooo cosy,they have a cuddle cup but are preferring to lay directly on the fleece.Next test will be its first wash,will update then,think I will buy another piece anyway,so one on and one in the wash ;Dsx
