I just looked this up, and I live in Canada and it is not available here. I think i wouldn't mind trying this, but by looking at the cost of the accessories it is a bit pricey.
My daughter did try to "potty train" her cat with something similar and it didn't work, ended up costing her as her cat didn't poop for days and ended up constipated. so other than a litter pan I don't know how much I would put into it.
I also had one of those pans that cleaned itself, my cat was terrified of the noise and wouldn't go near it.
So good ole pan and clumping litter for me at this point.
My old cat got scared of the Littermaid, so I don't know that I would buy this. Plus, I'm weird about sanitizing the cat box- I don't know that you could do that with this, but maybe I missed something.
I'm very into the concept, but it wouldn't work for my girls. One of mine has loose poop sometimes. The reviews on amazon say that if your cat ever has runny poo, your house will end up smelling like baked cat shit.
I also don't have space next to our toilets or washing machine to set it up. That was main deterrent.
