Well, he might get the message if he has to start cleaning the pee away.
Put your foot down ...
As far as the cat is concerned he seems to have a serious problem.
I take it you have checked the urine if there's blood?

Oh, man. Besides making sure the litter box is squeaky clean and there's at
least two of them, I don't know. If he's peeing on sacks simply because he
*wants* to pee on a sack, you can't "make" him stop. My cat did this with
towels. What I eventually did was deliberately leave one towel in the floor,
just for him. That way, he doesn't go on the carpet at least. I'm such an
enabler.

This is a bad situztion.  However, we shall purr hard for her safe
return. MLB

My dog had repeated UTI. Then it turned out that she had a bladder stone.
You may have to get the cat x-rayed. Such stones irritate and cause UTI.

Feliway is used for behavior modification and can be very useful in reducing
stress. It is available in plug-in diffusers (with refills available) and as
a spray. I used the plug-ins so it can be working all the time. A spray
version is also available. It is excellent for an occasional use, such as
spraying the carrier about 20 minutes before you take your cat to the vet,
but the plug-in diffuser is better for long-term use because it releases
premeasured doses. (In your case, I would definitely recommend the plug-in
version.) Refills can be purchased for the dispenser. One bottle lasts a
little more than a month.

I ordered mine from ValleyVet (http://www.valleyvet.com). They have better
prices than most others, and there is no charge for shipping (but you would
need to verify this because the "free shipping" is often based on a minimum
order). The last time I checked, they listed Feliway for $29.95 for a
diffuser with one bottle of Feliway. It is also available as a spray for
$15.95.

Here are a couple of other sources for Feliway:

www.petguys.com ? Feliway plug-in dispenser and one bottle = at one time,
they had a sale price of $20.99, so it would definitely be worth checking
www.petfooddirect.com ? I don?t have pricing information, but PetFoodDirect
has been a reliable source for me when ordering other supplies

Here is a link to a study by Ohio State University:

There is also a "cat attract" cat litter that some people (including my
sister) have found helpful if regular litter isn't effective.  I will be
glad to look up the source if you want the information.  I understand that
the same company now sells an "additive" to add to regular (clumping)
litter, but I haven't talked to anyone who has used that.

I hope some of this helps.

You need to take this cat back to the vet *immediately.* This is NOT the
behavior of a cat that is peeing out of "habit."  A cat with a UTI will
exhibit frequent urination (trying to pee in several places within just
a few minutes) which is what your cat is doing, and my guess is he is in
quite a bit of pain. It's especially likely because he recently had a
UTI. If he does have a UTI and is developing crystals, he could easily
become blocked and will DIE if not treated.

If you are feeding dry food, and especially free-feeding, you are
creating a climate where UTI's can frequently reoccur. Dry food has been
shown to cause or exacerbate urinary tract problems in cats, and canned
food is not only healthier, but a more species appropriate diet whereas
dry food is not. I posted an article about this awhile back that can be
found here: http://www.catnutrition.org/Catkins.htm
The rest of the site and the resoueces page are excellent and worth
reading as well.

Please get your cat to a vet right away and switch him to a canned only
diet to help prevent this problem from happening again and again.
