I want to love this... but it was a complete waste of money. I have a large cabinet set up just like the box this is suppose to go to and all. It doesnt help with my litter tracking problem whatsoever. Yes, it gathers a small fraction of litter, but thats it. Not only that, but the tiny hole on the bottom makes it almost impossible to completely clean out. Its easier to just take it outside, flip it upside down, and shake it out. In addition, if your cat accidentally makes a mess on the product  (mine coughed up a hairball directly on it) there is no way to remove the entire top. I had to try and clean in between the slats with a q-tip. Believe me, it was a hot mess. I wish I could get a refund. Im just glad I waited until it was on sale before I decided to try it out.
