we have a small house and can fit 4 litter trays in,they dont exactly take up much room!!as for the bath,i wouldnt think that was a good idea at all

we have 2 in our tiny bathroom,one next to the bath,one next to the loo.as for self cleaning trays,well its ot somethingi would bother with,there will be a lot of maintenence involved,may as well get normal trays!
