I bought one ten years ago, and then bought a second one in large.
These work extremely well for the initial cost.
It helps to clean them out daily and use fairly good litter.
The best method is to turn it over and almost upside down, then give the bottom a solid rap or two to knock the stuff sticking to bottom off.
I bought one for my sister and another one for my brother - way back years ago for Christmas presents.
At this point I still have one, it is on the patio waiting for me to retrieve it and put it back together.
My twenty pound cats used the bigger one but there ought to be a giant sized one for older arthritic cats.
I used littermaid - always buy the bigger one of this brand as well. I got angry with the stupid rake and gave the littermaids to my niece and went back to regular cat boxes do to a lack of funds.
Then I tried Littersweep but immediately took it back and got another Littermaid. They didn't have any Omega Paw - which is what I wanted.
Omego Paw is worth the money, works better is you clean it once a day, and sometimes it needs to be just plain cleaned out and sanitized by the sun and rain.
