We used a clean (new) baking sheet (not the non-stick one)

Thank you for the suggestion! My little guys kept burrowing under their green liners after they had pottied them. I made litter boxes with baking sheets, put a different liner for those, and gave them the green liners to just burrow with. It worked! They have not tried to burrow under the baking sheets and have not bothered with those liners. I am hoping Whyte will finally potty train, as well. Riley already was but then would burrow. ew.
