Spraying---also known as marking---is a common occurrence in cats. When a cat sprays, he is leaving a mark---or type of message---for other cats with his urine. During the spraying process, the cat will back up towards the object, hold his tail up in the air and spray the item with several short bursts of urine. It is more common for an unneutered male feline to spray. Tom cats are not the only culprits of this behaviour; neutered males and female cats can spray as well. Tom cats are typically unneutered outdoor male cats that may or may not have a home. Tom cat spray is a pungent odour that can drift into your home.
Create a solution of 4 cups of hydrogen peroxide, 4 tsp of baking soda and 4 drops of a mild dish-washing liquid. Use a hydrogen peroxide with a grade of 20% or 35% instead of the 3 per cent grade that is normally found in department stores.
Pour the solution into a clean spray bottle.
Gain access to the area underneath your home.
Spray the solution liberally onto the dirt under your home. As the solution dries, it will neutralise the odour.

Create a solution of 3 parts cool water to 1 part distilled white vinegar. Pour the solution into a clean spray bottle.
Spray the area liberally with the solution. For carpets, use a scrub brush to scrub the solution into the carpet. Allow the area to air dry.
Sprinkle baking soda directly onto the area. Leave the baking soda for at least a few hours but preferably overnight.
