There are multiple types of sprays you can use to lead to your cat spraying no more. First off, you may find cat urine repellant to be useful. Certain sprays, such as Urine Power Away, use concentrations of chemicals to fight the odor-causing bacteria. This leads to a good cleansing of the area that the cat has sprayed in, rather than covering the scent using another fragrance.
Secondly, you can use sprays such as “No-Scratch! Spray” to distract and repel cats away from certain areas. If such a spray is applied on a piece of furniture or area, the cat would not mark its territory on it as it will be repelled from the area due to the odor. This is a rough technique, but it may be useful.
