Urine marking (spraying) is a normal feline behavior that is unacceptable in the human household. Cats urine mark primarily to advertise their presence to other cats and to establish and maintain territories.
The most common triggers for urine marking include a new cat in the household, free-roaming cats outside or social conflict between family cats. However, other events such as a visitor to the home, new furniture or unfamiliar odors can also trigger urine marking. Sometimes cats urine mark if they are frustrated, such as when they are denied access to outside or haven’t gotten enough attention from the owner. Additionally, an anxious or fearful cat may urine mark to surround itself with a familiar scent.
Urine marking is much more common in unneutered males however females also urine mark. Neutering your male cat is the first thing you should try, however, a certain percentage of neutered cats continue to spray following the surgery.
The following list will give you some suggestions for dealing with urine marking. Many chronic spraying problems however, are difficult to eliminate. Management may be your best bet.
If the spraying is a response to cats outside, you should cover the windows or put something slightly aversive on the windowsill like a lemon-scented solid deodorizer. You should also discourage the neighboring cats from coming into the yard.
If spraying is a response to social conflict with other cats in the household, you need to work on improving the relationship between the cats. Make all of their associations positive using treats, affection and play. You should also provide the marking cat with “alone time” 4-6 hours a day, away from the other cat(s).
Provide an “environment of plenty” by creating multiple feeding areas, multiple elimination areas and multiple sleeping perches at different vertical heights throughout the house.
There are medications that may help control urine marking in your cat. The suggestions above should be attempted before considering medication. If you feel that you have tried everything and the problem still persists, consult your veterinarian about drug therapy. It is often the case however, that the cat will cease spraying while on the drug, but will revert to the behavior once the medication is stopped.
