Instead of using casters (with legs and/or platforms) for cages, go to your local hardware store and pick up freezer/fridge rollers. They can hold alot of weight and keep the cages close enough to the floor so the fuzzies can't get under them. I have used them for over 8 years and they are great! Roll the stack out to clean behind and sweep up any kibble that goes under! Vickie McKimmey Just a Business of Ferrets www.mindspring.com/~jbferret [Posted in FML issue 3076]
