Query: Very Poor Construction!

Giving this one star is too much! There is absolutely nothing good to say about this litter box. My frustration with the two to three times a day cleaning the mess and repairing jams, I threw the entire thing in the trash. I thought after happily using the Littermaid for my three adult cats for over six years, I would try the Petmate. Very disappointed!
