I have two litter boxes in the room for Byron, one in his ferret penthouse
and one in a corner on the room, for when he is out loose.  He uses both of
them, but occassionally goes behind the door.  I constantly clean the area
and try to get rid of the smell, so he doesn't associate the door with a
litter box.  Is there something I could buy to put down, like a powder or
spray, that would tell him to stay clear and that this is not a bathroom?
Any suggestions?
