Right now I have a quad sleeping in a log, and a pair sleeping in a cube. The pair take turns between the long pouch and the cube. So my suggies have tried those three, and the absolute fav might be the cube. They don't have a play 'n' stay hollow - maybe you should send them one and I'll ask them?????
