response to WHAT IS THE BEST KITTY LITTER? compressed wood fuel pellets available form fireplace stores. $4.35 for 40 pounds. I use a dish wash pan and about 1 inch to 1 1/2 inches for 5 ferrets. Less thrown around the place. Clumping can be swallowed and cause blockage and clay has some drawbacks. Newspaper print smells with 5 ferrets and costs too much. [Posted in FML issue 3106]
