Query: Great idea.

I just put the box together today, and have already tried it out. It works great. You roll the box and the clumps go into the bin. My only con so far are the clips. They are not easy for me to move. We have three cats that use the same box. We change litter once a week. I'm not looking forward to dealing with the clamps every week. One of our cats has odd pee and it makes the litter stick to the back of the box. I'm not sure how I'm going to manage scrapping the box everyday without taking the lid off. We'll see. With all that said, I'm still very excited about this cat box.Tip: roll the cat box over until it's just about upside down, then roll it back to the upright position and roll it the other way so the litter can fall back into the main area.
