Cats donít need high tech devices to communicate. In addition to body language, vocalizing, scratching objects, and rubbing, they use urine to broadcast their intentions and emotions. Spraying, which is one form of urine marking, is not hugely popular with people, especially when done indoors.

It can be difficult to tell the difference between urinating and spraying because some cats stand instead of squat while urinating. The smell and the amount of urine indicate whether itís urinating or a marking behavior. Spray is highly pungent because it contains pheromones. This unpleasant smell sometimes is the only indicator that cats have sprayed in the house. One positive note is that less urine is deposited when cats spray than when they urinate.
Kitties are sometimes caught in the act ó backing up to a vertical surface, treading with the front paws, and quickly twitching their tails while spraying. Simultaneously they may close their eyes.

Why cats spray

Urine is a powerful communication tool ó cats can tell a great deal about each other from it including age, sex, status, and sexual availability. Although adult cats of both genders, whole as well as fixed, might spray under specific circumstances, intact ones are most often guilty of the smelly behavior.
Whole males, as a rule, spray. Pheromones, released into the urine, advertise theyíre ready, willing, and on the alert for girlfriends. Additionally, spraying broadcasts clear messages to other male cats to stay away. Intact female cats spray too ó the chemicals in their urine indicate where they are in their cycle.

Spray from intact cats is more pungent than from those who are fixed. The unpleasant smell is easier to detect from a distance ó important for advertising for a special friend.
Although spayed and neutered cats arenít looking to connect with members of the opposite sex, they have other reasons to spray including:

  • Marking boundaries
    Spraying is the feline version of drawing lines in the sand and putting up ďno trespassingĒ signs. Kitties are territorial ó the far-reaching effects of the pungent urine lets other animals in the hood know the extent of their stomping grounds.
  • Reacting to neighborhood cats
    Inside cats sometimes spray around doors and windows when they see or smell unfamiliar cats hanging out around their homes. They spray to mark territories and because they canít reach the intruders to chase them away or engage with them. Often, the unwelcome visitors leave their own calling cards, which the resident felines smell.

  • Recognizing their own scents
    Cats sometimes will spray inside their territories so they can smell and recognize their own scents.
  • New objects and furniture
    Some cats will spray new furniture or objects that are brought into their homes.
  • Stress
    Insecurities and stress can trigger the unpleasant behavior. Some cats are more sensitive than others, responding by marking to situations such as other cats, household changes, owners traveling, illness, new household pets, and even schedule changes.

  • Mingling scents
    Some cats will spray their favorite peopleís belongings in an effort to mix scents together and create a bond. Another reason is for security. Stressed, fearful cats will sometimes spray objects that smell like their owners, helping the cats feel a little more secure.
  • Not adjusting to change
    Some cats do not adjust well to household changes, including problems between the humans residents, a new baby, schedule changes, moving, and remodeling.
  • Conflict resolution
    Conflicts in multicat households can cause marking. Stressed, anxious, and threatened felines will spray in order to communicate status and territorial boundaries. In theory, the smelly behavior might keep cats from fighting. Cats who engage in hostilities often are scratched and bitten. Settling wars through spraying is much safer.

Curtail the smelly behavior

The following tips and suggestions help stop spraying, and they also help stop the behavior before it begins:

  • Donít punish cats
    Never punish cats when they spray. Donít yell, rub noses in the urine, or hit them. Those responses will cause kitties to feel more stressed and escalate behaviors. Sadly, it also breaks the bonds between them and the punisher. Kitties arenít being bad ó they have good reasons for marking. Instead, identify the causes for the behavior and address them.
  • Use an enzyme cleaner
    Thoroughly clean marked areas with an effective enzyme cleaner. It might take a couple of applications until the smell is eliminated.
  • Change mental connections
    Change your catís association with the targeted areas after the areas have been cleaned with the enzyme cleaner. Do activities she enjoys such as playing, petting, and clicker training on the areas. Placing toys and scratchers near them will also change how she relates to the sprayed spots.

  • Use synthetic pheromones
    Using synthetic pheromones around the marked areas can help calm and relax your cat.
  • Close doors
    Temporarily keep your kitty out of the rooms that are being sprayed.
  • Interaction
    If your cat is spraying a family memberís belongings, encourage the person to feed, play, and interact with the kitty every day.

  • Address intercat issues
    Increase the resources to reduce the competition in multicat households. Provide more vertical territory, hiding places, scratchers, and toys throughout your home. You might need to add feeding stations, placing them a distance from each other. Make sure there are enough clean litter boxes ó one per cat, plus one, and place them in different areas of your home. Sometimes separating warring cats from each other and gradually reintroducing them will stop the squabbling and the marking.
  • Discourage neighborhood cats
    Keep neighborhood cats off your property by placing safe deterrents around the outside perimeter of your home. Temporarily block your kittyís view of the unwelcome visitors by covering windows. After the intruders stop visiting, uncover the windows.
  • Spay and neuter
    Although all adult cats can spray, the chances of their marking are greatly reduced by spaying and neutering. In addition to eliminating the reasons to mark, spaying and neutering also helps curtail hostilities.

  • Daily interaction
    Help your cat feel more secure and less anxious by doing activities she enjoys every day, such as playing, treasure hunts, and clicker training.
  • Vet check
    Before assuming your cat has a behavior challenge, have a veterinarian examine her in order to rule out any possible medical problems that could be causing her to spray.
  • Gradual introductions
    Newly adopted kitties need to be separated from your resident felines and gradually introduced. It might take a month or longer to introduce them to each other with a minimum of stress.

Although all cats can spray, it is a behavior that intact cats are more likely to engage in than those who are fixed. Once the reasons for the smelly behavior are identified, you should be able to stop it or at least reduce the occurrences by addressing the causes and modifying the environment.
