okay so i am thinking of this new idea, and im wondering if there is something wrong with it that i may be missing. okay, well the basic idea is, to put strips of velcro around the length of the wheel, and put velcro on a strip of fleece (cage liner) and velcro it on. then, if you wanna clean it, just stick it in the washer and velcro it back on. is there something wrong with this idea??
