Thanks.

So has mine, in the past.  Unfortunately, in the last year or so one (or
both) of the cats has taken to peeing on the couch :-(  Since it is a futon,
it is virtually impossible to get to all of the problem with even the best
enzymatic cleanser :-((  The problem is behavioural, not medical, but we
haven't been able to find a way to solve it.*  The only thing we've been
able to do is try and bar access to the most common sites of "innappropriate
behaviour."  ie--she (they) also tend to pee in the highchairs if given the
chance, so when the boys aren't in there we rest the trays in the seats in a
way that doesn't leave room for the cats to get into them.  But the sofa is
much larger, and trying to effectively prevent the cats from misbehaving on
it has meant that it's not accessible to people either.

*The cats basically live in the living/dining room level of my split-level
home.  I have 14mo twin boys.  The living/dining room is open concept, so
there is nowhere we could put a second litter box for the cats.  The litter
box is kept in the bathtub, where the dog and the toddlers can't mess with
it.  But this means we can't try "retraining" (as some people have
suggested) by confining them to the room with their litterbox because that
would turn our only bathroom into a cat-jail.  And finally, I admit it, with
two cats, an energetic dog, and two kidlets who learned to climb before they
could walk, I usually don't have the time to sneeze let alone the time to
retrain cats :-(  I don't feel good about it, but there it is.  I will
*not*, as some people have suggested to me, get rid of my cats--they aren't
disposable, just occassional PITAs.
