Hello! Are you using the fleece for the whole floor or just part of it? If you just use it for part of the cage I would recommend an old blanket. If for the whole cage then maybe buy from wilko? I was looking at them the other day and they were cheap but looked quite good quality. Some nice designs too. Maybe look in pets at home? If you are, again, looking for just part, they do guinea pig fleecy beds. Sooo cute but a little expensive! I would wash a fleece every 2 days ish, as if you leave it for longer, everything will stick to it and it will have to be thrown away!
