I'm thinking about making a third set of liners so that I can save up and do a larger load of laundry at once. Three cages, three male chins, six liners, changed every 1-2 weeks, no shavings pan. I tend to get some odor at about 2 weeks when I'm being lazy, so I make an effort to do it weekly. The biggest problem is getting rid of the hay that sticks to the liners - I have a balcony (currently full of stuff) but no yard to shake it out in. Still trying to figure out the best way to deal with that, I hope I figure it out before my washing machine gives up on me...
I HATED dealing with shavings. Messy. Chins would throw them out of cage (so hay, poop, AND shavings on the floor). Needed big garbage bags. Took more time to clean cages. etc. Fleece has its disadvantages, but thus far, I prefer it. I've been using fleece for almost a year now, I think.
