Tomcat spray is a serious problem because it contains odorous materials in addition to urine. If it’s visible the sprayed surface should be washed off. Unfortunately this won’t take care of the spray that has penetrated the surface. About the only way to effectively treat the problem is to spray the area with a quality odour remover several times until the odour is controlled or eliminated. We recommend Odorex® Animal Odour Eliminator. Spray the surface until it becomes just wet enough so that the odour control product starts to run. On porous surfaces such as carpet we recommend Odorex® Deodoriser For Cats. Place a clean piece of cloth over the affected area and stomp the cloth to force the fluid down into the fibres. Allow the area to dry or better still mop up excess fluid with a clean, dry cloth or towel and repeat the process.
