These work great the high walls keep liter in but the low entice let's even older cats get it. Easy set up and super easy disposal. Not to mention that the company is great to work with. I have contacted them a couple of times and they have been extremely helpful.
The Cats Desire Disposable Cat Litter Boxes are the BEST. I am disabled and even I can take care of our 2 beautiful cats. They are easy to put together and dispose of when needed. I can't say enough about theses cat litter boxes.
