This thing seems to fit okay even if there are no slots for it to clip onto on the ScoopFree Litter Box that I bought. But the really big problem is that they put a sticker on the inside of it that tears and makes a horrible mess if you try to remove it. I had to spend at least 30 minutes scraping to get the junk off and then it left a mess of glue and scratches behind. You can use something like WD40 to dissolve the glue, but then you gotta scrub it really dang well to get rid of the smell 'cuz cats are really picky with the smell of the place they do their business. And that still doesn't get rid of the scratches from scraping that stupid label out. Who the heck thought that sticker was a good idea? How is it you cannot figure out what adhesive to use in this day and age?

The Cover came earlier than promised, it was an exact fit , sturdy and my cat enjoys his privacy

The cover works great. I don't have cat litter everywhere now. The cover is very durable and stable.

It works well but a little difficult to place in slots.
