Query: DON'T WASTE YOUR MONEY

I HATE IT!!! It's actually worse than a regular litter box. I use the clumping litter that they recommend, and it clumps all right, and then sticks to the scrapping tines. Also, the scrapping tines are a good 1/2 inch above the bottom of the box, so there are always clumps and lumps left in the box. It cost a lot of money, and I'm throwing mine out with the garbage.
