Answer
Marie,

Improper elimination is the number one reason a lot of cats are put to sleep...and it is unnecessary. There is always a reason for the cat's behavior. Though sometimes you need to be a detective to figure it out.

First it could be a medical issue. He may have a Urinary Tract Infection or Urinary Crystals. Both are common, and both are painful. The cats associate that pain with the litterbox and go elsewhere. Urinary Crysals can cause a complete blockage if not caught in time and is always fatal to male cats. He may also have a kidney infection. I would have him checked by the vet before assuming it is a behaviorial issue.

Are there cats out the window that the cat can see but can't get to to defend his territory? That is one reason that could cause his behavior. Blocking the window helps.

Sometimes too, cats don't like where their litterbox is located. They like privacy. They also may decide they don't like the litter you are using or the litterbox becomes too small for their liking. Try getting some children play sand from Home Depot or a buiding supply store and see if he prefers that and a bigger litterbox with deeper litter in it. That will tell you if it is a litterbox problem.

There is a very popular cat calming spray and plug-in you can use called Feliway. It is available at pet stores or on-line. It copies relaxing pheromones that cats produce from rubbing their faces on things. There is also a calming product that you can add to your cat's food or water that reduces anxiety called Bach's Rescue Remedy. It is available on-line and in health food stores. Here is a link about it: (copy and paste, or type the whole links into your address bar) http://www.bachflower.com/Pets.htm

If your cat is still stressed and the behavior continues, the vet can put him on "kitty Prozac" for a short term (usually 2 weeks). It is very popular for calming cats with emotional problems. You may want to speak to the vet about it.

And here is some helpful (I hope!) information on cleaning cat urine:

HOMEMADE CAT URINE REMOVER

1 quart of 3% hydrogen peroxide
1/4 cup baking soda
1 teaspoon of liquid soap

Gently mix all ingredients in a non-metal container. Do not mix or shake vigorously! The mixture is best used when fresh but can be stored. DO NOT keep mixture in an airtight container as baking soda and hydrogen peroxide when mixed together release a lot of oxygen and can cause an explosion.

The recipe is effective because the reaction from mixing hydrogen peroxide and baking soda produces large amount of oxygen. The oxygen molecules bond to the thiols, breaking them up into carbon dioxide and ammonia which evaporates quickly thereby effectively neutralizing the thoils and their foul-smelling odor.
Always check for color fastness as hydrogen peroxide can be a bleaching agent. If you don't know where an odor is coming from you might need to use a small battery operated blacklight called a 'Stink Finder' (PetSmart, Petco, etc.) at night to find the soiled areas.


HOW TO REMOVE CAT URINE ODOR FROM CARPETS

FOR INDIVIDUAL URINE SPOTS ON CARPET:
If fresh, sop up as much cat urine as you can with a paper towel first. Use a spray bottle to saturate the spot completely with the recipe - do not blot. The recipe must penerate the padding and possibly the floor boards underneath, where the urine has penerated for it to work. Wait 24-48 hours until dry then vacuum. If the urine odor is still present - repeat the procedure. It usually takes 2-3 applications to completely neutralize the cat urine odor.

FOR LARGE AREAS OF CARPET:

You can use a carpet cleaning machine  using the recipe instead of the shampoo. You will need to make several gallons of the recipe depending on the size of the carpet. Don't use the vacuum part of the machine - you will want to let the solution soak and dry for 24-48 hours before vacuuming. Most carpet cleaning machines are not made for this use and baking soda can clog the nozzles of the machine.

A 1 gallon garden bug sprayer (Home Dept., etc.)  works great too.  Rinse the nozzle out frequently by filling the tank with hot water and spraying it in the  bathtub. If using the sprayer, saturate the entire carpet with the recipe, let dry for about 24-48 hours, and vacuum. You will have to probably repeat the procedure again. Areas heavily saturated with old urine may take 3 applications over a week.

If the cat urine is old and dried, the smell will probably be worse a day or two later. This is because you are rehydrating the uric acid crystals in the urine to neutralize them. The smell will get better with each application!

MATTRESSES:

You must saturate the spot throughly to get deep down into the padding and springs to neutralize the urine. If the cat has urinated alot in one spot, the mattress can be soiled all the way to the other side! Let the area dry for 24-48 hours without bedding then reapply if necessary.

SOFAS:

The same directions as above  but always check for color-fastness in a hidden area before using. Cotton is used in alot of upholstery fabrics and is easily bleached. If your sofa pillow cushion covers can be unzipped and taken off (must be color-fast and washable) you can put them in the washing machine using the instructions for clothing and bedding.

CLOTHING, COMFORTERS, AND BEDDING:

Put the items in the washing machine and pour in enough of the recipe to cover throughly. This might take a few gallons depending on the size of the load. Soak for at least 24 hours. Rinse and rewash using normal washing detergent. If any of the odor is still present, soak again for 24 hours, rinse and rewash.

A small area on a comforter can be spot treated by saturating the area throughly, letting it dry for 24 hours, then washing the comforter normally in the washer with detergent. Always check for color-fastness before using.

AREA RUGS:

They can be spot treated with a sprayer or put in the washer. Test for color-fastness before treatment.

HARDWOOD FLOORS:

When cat urine seeps into wood flooring it causes the fibrous cells in wood to swell and warp ruining the flooring planks. The only way to fix this is by replacing the wood. You can treat the wood with the cat urine remover recipe but wood is preamable and it could make the wood swell further, causing further damage.

HARD SURFACES:

Spray or mop the area soiled with the cat urine. Saturate it completely and let the area dry for 2-3 days.

I hope this information helps.
