Also, for layering I use the waterproof mattress pads (got several on sale at Babies R Us) and cut them to size for the floors of our C&C cage. Then I use one layer of towels for the middle and top floors (they pee less on those floors, plus I use the fleece/towel pee pads for added layering in the corners), and two layers of towels on the bottom floor. I had thought about getting the UHaul pads, but I read info pro and con on them. I had already purchased brand new towels for the cage ($1.97 each at Walmart), so I didn't want to make another purchase. For now, towels seem to work just fine. When I wash everything, I use unscented laundry detergent, a full cup of white vinegar, and I sprinkle in about a quarter cup of baking soda. I wash the fleece separate from the towels...I have too much bedding for it all to fit in one load.
