HI, THIS MAY SEEM A VERY STUPID QUESTION BUT I HAVE A ROTASTACK HAMSTER CAGE WITH A BIG SPIRAL TUBE AND MY HAMSTER KEEPS WEEING IN THE BOTTOM OF THE TUBE WHICH IS THEN OBVIOUSLY LEAKING ONTO THE TABLE. IS THERE ANYTHING THAT I CAN DO TO DISCOURAGE FLUFFY FROM USING THE TUBE TO WEE IN. SHE DOESN'T POOP IN IT JUST WEE BUT ITS RATHER UNHYGENIC LEAVING A PUDDLE UNDER THE TUBE ON THE TABLE. DOES ANYONE HAVE ANY IDEAS AT ALL....ANY ADVICE WOULD BE FAB THANKS.
