"I purchased this in April and finally got it in August. SAVE YOUR MONEY!!!! It is the worse cat box I have ever used!!! It is so much trouble and ridiculous to use! My cats make 10 times more mess even with the cover. You basically cannot move it at all or else the slits shift and cat litter spews all over. They are wrong in saying the sides keep you from turning it the wrong way when you have litter in it and trying to put the one on the bottom it doesn't work because of the weight. Plus everything sticks to the sides and good luck getting the litter clumps out of the slits!! GIANT PAIN to clean every single time you sift! They gave me all kinds of rules and steps to follow when I complained. Only used it for 2 months and couldn't take it anymore went back to my old box with a liner HELLO easy! They also would not even consider giving me my money back!!!"
