I have the Trixie Wooden Wheel, lined with cork, and it's wonderful. The only sound is her little feet pitter-pattering. (I have the 28cms one for a Syrian)

My first one developed a bad wobble, but the second one is fine. And zooplus refunded me the money on the second one, when I explained the problem. My OH managed to fix the wobble, so now I have one for the bath tub as well
