Hi Todd,

(A small variation on this has worked for me)

Take cat to the vet for a once-over. If he's been living in a stressful
environment, his immune system's toast and he could have a urinary tract
infection.

On the way home, pick up a doorchain, a couple Milkbones and some beer.

When you get home, install the chain on a suitable room (preferably a
bedroom or study with a couch sort of thing); clean all the doghair out
and deodorize it somehow.

Throw in a cardboard box with a towel in it if necessary (not the
litterbox, and not the food dish). You won't be forcing the cat to move,
just giving him a place that isn't automatically dominated by the other
(larger) pet *as well as* the shared area. Cats are *very* territorial.
The dog has his/her walks with you.

While the cat's checking it out, slip the dog a Milkbone.

Have a beer.

doorchain - *$5*
Milkbones - *$3*
beer -     *$10*

Happiness that your cat isn't stressed out and will eventually befriend
or at least ignore the dog - *Free*

Opening the chain the first time the cat teases the dog 'cuz pussy
thinks he can get away with it - *Priceless*

If he's not urinating at all or in very small amounts, run the cat to the
vet.. he could be blocked.. a very dangerous condition.  If he does urinate
in regular amounts, but just spends most of his time in the box, Id
recommend finding a way to get the cat some separate time from the dog.. a
tall (five feet or more) cat tree, and/or a small cat door into a room that
you normally keep closed so the cat has his own space away from the dog
where you can keep the litter box and food..

Extreme solutions.. find a veterinarian who specializes in acupuncture and
herbs.. you'd be amazed what they can do..  Get another cat to help out your
kitty so it would be two on one.. or find a new dog free home for the
kitty..

Good luck!

If he's in the litter box and not going, he's trying to tell you something.
Does it seem like he's straining to go?  If he is get him to the vet ASAP,
if he is blocked and it's not cleared in 24 hours it can lead to death -
they become toxic from the back-up of urine.  Not to mention how absolutely
uncomfortable it has to be for him.  If you are not sure, call your vet,
they'll probably think the same and tell you to bring him in.  This is not
something to "wait and see" with.

You did not mention if you just brought him home or if he and the dog have
been together for a while now.  If they have been, I'm going with my first
instict - go to the vet.  And if he and the dog are new to each other, I
can't see the cat hanging out in the litter box, more like under or behind
the furniture.

Good luck and let us know.
