This is the best for keeping the cage clean. I change these out, and then I don't have to flip the flippers as fast. They are so soft, great padding and sturdy. My piggies loves to sleep on them and prefer them over any other potty pad I have bought before, because they are thicker and softer. I use them everywhere in the cage, under the beds, under waterbottles, on the loft. I highly recommend.
