It amazes me how we can all use the same things and get such different results! I switched from fleece to vetbed and have seen no change in upkeep, odour, boys' dryness, nothing really.
I only switched because I wanted a more "cushy" surface for them. The bottom of their hutch is open onto tile floor and the 2nd story is a wood floor so I thought the surface hardness can't be very comfortable.
