Mine were never fully potty trained, over time they learned thats its not okay to poop on their owners though. They usually give you a sign that they want to poop and we rush them over to their cage, other times they can't hold it in. When their on our sofas they walk backwards towards the ledge when they want to go potty, so we have to stop them and rush them to their cage. Again, we can't catch it everytime o.0.
What we did is buy a cheap rug to place under their cage because they have a nasty habit of aiming the wrong way when we open the top up. If they do it on the sofa we just clean it up with some lysol but if it looks like their about to go potty we pick them up and rush them over to their cage, but its not always possible
