male cat urine marking

Question
Hi! I have a ten year old cat that I rescued when he was about ten months old. He wasn't neutered until he was a year due to some medical problems that needed to be addressed beforehand. My problem is that for the past ten years he has been spraying in the house! I love him to death and would not get rid of him ever but I would like to find a way to at least curb his behavior. I have tried confining him in the basement where his litter boxes are(I have three other cats and a total of four litter boxes) and I've tried feliway spray and plug ins.(I have even tried chlomaprine? I think that is how you spell it. But it changed his personality too much) If I let him outside a few times a day he will usually do it out there and come right back in. If he does it in the house and I find it he will hide so he knows he is not supposed to do this. Lately he has been spraying inside the litter boxes which I would prefer but I have to lock him up at night because he will spray every night(and his favorite spot is on the stove!) if i don't. At this point I have it under control but I was wondering if there is anything that can be done to stop his behavior? I know he does it because he was neutered too late and it is a natural cat behavior but he can cause fights between me and my husband. I will not get rid of him and my husband knows this! He is not declawed! That is incredibly cruel! Any advice you could give would be appreciated. I feel like I have tried everything! Thanks in advance.-Jenn-

Answer
Jenn,

I know the cat has been seen by a vet, but has he checked for a urinary tract infection, urinary stones, or kidney problems (or other kidney problems including a previous injury to the kidney area or something inherited.

I will include some good articles on improper elimination that may give you some ideas: (copy and paste or type the whole links into your address bar)

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.
