I am so glad we changed to fleece. I only tolerated the aspen and carefresh for a short time. I could not stand it sticking to everything it came in contact with. We have 8 piggies, so in total we have 5 cages. That does make the job a bit harder, but on a small scale it will be nothing compared to other choices. Just think of your piggy and how it wont have to lay in its pee all the time. Your piggy will bless you with many many popcorns also upon the arrival of fleece. You wont regret the switch.
As Bdmellohead suggested though check with your mom first about the washer and dryer.
