Marlow is inside since this this morning. He has been hanging out all day in the basement.We think he went out early this morning only for a restroom break. He has checked out Sasha's litterbox a few times. He has seen Sasha use the litterbox (Sasha didn't see the humor when Marlow tapped him on the shoulder as he exited the covered box, Marlow sitting on top of it). And I put a box for him in the basement. Will he figure it out?
