Automatic Litterbox Central

Hi !
I'm from Quebec, Canada.
I speak french, so please sorry for my English

I have 2 cats.
1 male siamese (4 years old)
1 male Somali (2 years old)

I live with my boyfriend, and we clean the litter box (a big litter box
with a hole on the top!) twice a day. But.. We miss it sometime.. so we want to find the best automatic litter for us.

The somali cat make a big mess when he scratch the litter. So that's why we
have a litter that have a hole in the top (not in the front) so he can't trow
all the litter on the floor.

I heard for the litterloo, and I saw the video. I love it !!! It's what I
want. But the problem it's with the tornado cat the
litter will decorate the floor.. -___- "
I have to find something to that. I want the litterloo...

But I will read you comment about all the other automatic litter box maybe I will find the good one.
the litterloo is not to sell yet..
