I posted a while back about Tycho (18) and Ginger (11) peeing outside
their boxes on occasion.  We have 2 litterboxes in our office room on
the upstairs level of the house.  The inappropriate pee was in that
same room, and also in our living room downstairs.  I finally caved in
and put a litterbox in the laundry room,  which is on the same level
as the living room.  I put it in the closet, and just leave the door
open.

Well, it has now been about 3 weeks with no pee accidents.  I hate to
jinx myself, but they both seem to love using this downstairs box.
Maybe Tycho resented having to walk upstairs all the time, so he peed
outside the box to make a statement? Who knows... but maybe this info
could help someone here.
