It is basically an overpriced storage bin with a hole, but those ribs really do the best job I've sen of cleaning their paws. There's a lot of litter trapped in there when they use it. And the design keeps them from kicking litter out or "missing" like Ivan does (eeeeeeeeww).
Looks good to me - - seems like it's a regular tub with a lid with a hole cut out of it! I guess if the cat can "jump" out it would be great! I've not seen this kind before.
There's some use -- I've got two now, but Ivan is still avoiding it. I'm going to gradually switch all 5 boxes over the next few months. It definitely keeps the mess down.
I've seen one of these before but never knew if Marilyn would catch on to it. I had no litter box for her for 2 hours once and she waited patiently and when I brought in her new box...it wasn't even set up and she went automatically. Goofy girl.
