Many cats use urine to mark their territory. This behavior is called spraying. Instead of squatting and urinating in a puddle, the cat will raise its tail and squirt the urine backward toward the object it is trying to mark. Both males and females spray.
As a rule, cats will start to exhibit this behavior when they feel their territory is threatened. For instance, some indoor cats may feel threatened and start spraying in the house if an outdoor cat makes its presence known at the window.
Cat Urine
Cat urine actually glows in the dark, so if you know it¡¯s there, use a UV light to mark the spot. Cat urine is difficult, but not impossible to remove. Be sure to thoroughly clean soiled areas of carpet with a commercial product designed for that purpose (ask at your pet store). If the scent is not eliminated, the cat may return to the scene of the crime and repeat the offense. A clean, strategically placed cat box should prevent this problem. Some cats require privacy, so a box placed in a high-traffic area can lead to trouble.
