This is not an original idea, but I think it is worth sharing. I for one hate kitty litter trails on the floor. Get a Rubbermaid container 18-20 gallons ( $3.99 in Walmart) Cut a 8-9 inch hole in the top and fill the bottom of the container with your favorite litter. Put the top back on and you have a "top loading" litter box. We set it up about a week ago, and 4 of our 7 cats choose to use that one regularly. It took a few days for them to get the idea, but it finally caught on. There is so much less litter trail from that one than from the "front loading" one. Three of our cats continue to use the traditional one. But any reduction in the mess is appreciated by me
