I'm having this exact issue. I have 4 male tomcats vying for my 1 year old cats affection. My problem is a bit different beings that I have a cat and she is about to get spayed in a few days so that's why I have the males in my back yard, fighting, and spraying like crazy. Needless to say my house downright stinks. After lots of research I have found some pretty good ways to clean up the stench and to prevent it.
White Vinegar is that one solid ingredient that most grandmothers use and it does the trick. Take 1 part Vinegar and 2 parts WARM water in a spray bottle and go around spraying the infected areas while scrubbing away the sprayed areas.
Another spray you can make is 15 ounces Hydrogen Peroxide, 2 Tbl Spoons of Baking Soda, 2 squirts of dish soap. Very important to use a disposable plastic container and spoon to mix solution. Scrub and rinse with WARM water.
Bio-Zet is a laundry detergent that is used in Australia apparently. I've never heard of it till now, but have heard great reviews about it's ability to remove cat urine or spray from fabrics, clothing, and upholstery. I will be buying this and using it for the rugs outside my house.
Do not use products containing ammonium, this will entice the cats to spray even more! As if we want that, right?
Prevention for inside the house: This also applies to people who have indoor cats in their home
First of all: Cleanliness, cleanliness, and more cleanliness. Cats are very clean animals and need their litter boxes, etc. to be nice and clean.
Having several litter boxes throughout the house in the affected areas may help with spraying. Putting lemon, orange peel, lavender, and I believe it is Eucalyptus scents where the cats have been spraying will help to detour the little tigers. Also putting food, sand paper, or plastic bags in affected areas may help too. If you have cats outside your house trying to get at your cat inside the house such as is my situation, block the view of the outside world. So your cat doesn't feel threatened and feels the need to spray as well adding to the disgusting smell.
Prevention for outside:
Lemon, lavender, orange peel, and eucalyptus scents once again. The cayenne pepper and water as someone stated earlier will definitely do the trick, but use caution as someone stated can cause blindness in cats.. I would say the cayenne pepper and water would be good just to spray on the walls of the house and not the ground (could help to avoid the kitties stepping in the stuff too and causing blindness).. Since when a cat sprays they spray vertical up onto walls, furniture, etc. I would avoid using the powder version of the cayenne pepper to help avoid kitty blindness.
The biggest prevention of all is get your females and males spayed and neutered. This helps eliminate spraying, the excess population of stray kitties, and health problems associated with the reproductive organs. Do not use the excuse that you do not have the funds to spay or neuter your pet. There are plenty of programs where there is zero to little cost to have this surgery done and if you can't afford the proper health care of your pet.. You should maybe altogether rethink the decision about getting a pet.
If none of the tactics work above, take your pet to their local vet. There may be an underlining issue that is causing the your cat to spray.
Best of luck from one cat spray sufferer to another!
