Put a lot of newspapers around overlapping one another. Put the group of papers at the door that your yt will go outside to do business. Then each day remove a piece of paper that is furtherest from that door. As you reduce the area to a very small section that is right by the front door you are planning to use to go outside. At some point you could possibly remove the indoor paper section all together with some success to have your yt go outside. Good luck, keep trying.
