Hint: you can actually teach it to poo at a designated location. e.g it tends to go to the same location as WC but the smell is actually a factor. So if it WC on top of an item (in this case you can train it to do it on a carpet and then place that carpet at a corner of the room. That can eventually become where it goes for WC. Some other animal who wants to keep their living area or feeding area clean ~ also does the same.
