A. I am assuming you mean cerebellar hypoplasia (CH).
I found this amazing website (http://lifewithchcats.com) where you can find many options in terms of litter boxes. Just click under the section topics and tips and select litter boxes. There are different options described in details.
In the website you can find as well an endless number of tips on how to make their life easier. It is really a great source of informations and clever tricks!
