It might sound funny but we have been working on training Sheldon to come out of his night box, shed, or his burrow by knocking on the wood floor or fence. When I first started doing it I thought it was a fluke when he would come out. But he consistently comes out to greet me or my husband when we knock. It doesn’t hurt that we rewarded him with treats every time he came out. The treats where things like rose of Sharon flowers or pumpkin/Zucchini blossoms. I think it has a lot to do with the vibration he feels when we knock. The reason I started doing this is he will eventually get to big for me to pick up and I want a way to get his attention and have him follow me. ??❤️
