Hi all I have been reading about the "cage clips" and such, to keep litter pans in place. We went to our local home center, and bought Velcro strips, which we applied to the bottom of the pans, and to the cage bottom. Try as they may, my critters have never budged the pans again. When you need to clean, they lift right off. Hope this helps. John [Posted in FML issue 3097]
