I really love the fleece and have been usuing it for a few months. To me its so much easier to just pick up some towels and fleece and throw them in the washer then scooping a ton of shavings that smell and fall all over my floor.
Also i changed to fleece and carefresh because my guinea had mites and the vet said i should get away from the woodshavings because bugs grow more easily in the shavings and they can also cause respiratory and skin problems in the guinea pig.
So yeah i can understand the not wanting to wash the fleece all the time but i would steer clear from the wood shaving/pine/cedar chips. and go for carefresh or something of that nature
