They are amazing, I had a 2x5 and enlarged to a 2x8. My Fleece Flipper's are so easy to put together (board/2 pieces U haul and just slide the Fleece cover over, so easy). With my Stick Vacuum clean up is a breeze or dust pan, but getting under my wide loft the Stick Vacuum makes it really easy. I also love that I can wash the three outer ones (under the Fleece Forest and wide loft) that they sleep/use the most, and put them back in the middle, flip and flop and keep clean very easy. I don't have to wash all eight of them at the same time, which makes washing really nice and easy. I just love them. For their wide loft I use the paper litter/bedding and they use that the most for going to poop and pee. Makes the litter last a long, long time.
