Why Cats Spray


Even though you may not be able to see it, if your cat sprays in your home you can definitely smell it. The unmistakable odor indicates all is not peaceful in your cat’s universe. When a cat sprays, it can put everyone in crisis mode and it can put the cat at risk of being relinquished to the shelter, given away or sadly, even euthanized. Many people don’t understand why cats spray so they don’t understand how to effectively deal with it.

Many people misunderstand the motivation behind spray-marking behavior. All-too-often, cat parents simply label the behavior as territorial marking but that isn’t the only reason cats spray. Unless you can uncover the true cause for the behavior, you won’t have much success in stopping it. So it’s time to sharpen your detective skills and do some undercover work.

Note: whenever you’re dealing with any behavior that involves a cat not using the litter box, it’s crucial you have him examined by the veterinarian. Even if you’re sure the problem is behavioral, it’s important to rule out underlying medical causes.

Spraying vs. Indiscriminate Urination

To start with, you need to know that there’s a difference between spraying and indiscriminate urination. If a cat urinates outside of the litter box it doesn’t necessarily mean he’s spraying. These are two different behaviors and can have different causes. Indiscriminate urination is usually done on horizontal surfaces. Spray-marking is usually done up against vertical objects but some cats will spray regardless of whether there is a vertical surface present. In this case, the sprayed urine will form a thin line as opposed to the typical puddle during urination.

The posture for spraying is different from normal urination. When a cat sprays he typically backs up to the object, twitches his tail and begins treading with his front paws. He may also close his eyes while spraying. When a cat (male or female) displays normal urination, he usually squats.

When a cat indiscriminately urinates there may be an underlying medical cause or the conditions in the litter box may be unappealing. Even if the box is kept clean there may be something about the set-up that’s not appealing. There could also be something going on in the environment causing stress to the cat or making him feel as if it’s not safe to use the litter box.

Communication is Why Cats Spray

When a cat sprays, it’s a form of communication. Surprising to many cat parents, both male and female cats can spray. I’ve seen so many cases where cat parents completely overlooked the female cat and were convinced (incorrectly) it was the male doing the spraying. The pheromones in urine spray reveal lots of information about the sprayer. It’s the feline version of a resume. Spraying should be viewed as an outward sign that a cat is communicating something. It shouldn’t be viewed as a bad or spiteful behavior. Even though we certainly don’t like the idea of a cat spraying inside our home, it’s important to remember that it’s a normal reaction to particular situation in the feline world.

Some common reasons cats spray:

  • to define the perimeter for other cats
  • to create a familiar scent in his territory
  • Some cats will spray a family member’s belongings as a way of self-soothing by mixing scents
  • A cat may spray a family member’s personal belongings (such as a pillow or dirty clothes) as a way of creating a bond
  • A cat may spray a family member’s belongings if that family member’s schedule has changed or something else about about the person’s behavior is different
  • A cat might spray a family member’s belongings if he isn’t sure whether the person presents a threat
  • Since scent and familiarity play important roles in the feline world, some cats spray new objects brought into the environment
  • A cat may spray if he is denied access to another cat who may appear to be a threat (typically this is caused by the appearance of an unfamiliar cat in the yard)
  • A cat might spray if anxious, even if there doesn’t seem to be an obvious trigger from a human’s perspective
  • Cats may spray as a challenge to another cat
  • A cat may spray as a victory display after a hostile altercation with another cat
  • A fearful cat may spray only when there are no other cats or humans around
  • Intact cats spray when looking for mates


Confident and non-confident cats spray. A confident cat may spray as a grand display of his victory after a confrontation with another cat. A less-than confident cat might spray-mark as a form of covert aggression. It’s a way of giving a warning without actually having to risk a physical altercation.

The sprayed urine reveals information such as age, sex, sexual availability and status. These are important facts when it comes to cat-to-cat communication, especially in an outdoor environment where close encounters could result in injury or death.

Not all cats spray and if you gradually ease your cat through changes in his life such as the introduction of a new spouse, new pet, new baby, new house, etc., you’ll greatly reduce the chances that he’ll feel the need to spray. And of course, if you have an intact male cat you stand a 100% chance of spray-marking behavior so it’s a very wise idea to have him neutered. If your intact male is currently displaying spray-marking behavior, having him neutered will, in almost all cases, stop the spraying behavior.

Managing a Sprayer

If you have a multicat household, the first step is to identify the sprayer. Unless you’ve actually witnessed the cat spray-marking, the most reliable form of CSI is by using a video surveillance. Set up a motion detector camera, use a webcam or you can even put a kitty cam on your cat’s collar. The latter won’t show you the spraying but it’ll hopefully show what the sprayer was reacting to when he felt the need to mark.

The targeted areas need to be addressed:

  • Clean the soiled area with a product labeled for cleaning and neutralizing cat urine
  • Change the cat’s association with that area by engaging in playtime there so it becomes a positive location
  • Use clicker training to click and reward whenever the cat walks by the area without spraying or walks away from an area when called
  • Use a synthetic pheromone spray near the targeted areas so help change the cat’s association
  • To prevent further damage to carpets or furniture, you can cover the area with a shower curtain liner temporarily
  • In some cases, the area may need to be closed off completely while you work on behavior modification

If your cat has targeted one or two areas repeatedly, place litter boxes there that have high sides (but not covered boxes) because the cat may be satisfied with spraying inside the litter box. You can use a plastic storage container (Sterilite makes great ones) and just cut a low opening on one side

Pam Johnson-Bennett's works are staple recommendations for my cat clients. Her books are highly readable and contain information based on the true science of cat behavior.

If the spraying is due to the appearance of an outdoor cat, you’ll need to block viewing access. Cover the bottom on the windows with an opague window paper that will allow the light to come in but blur your cat’s view of any feline interlopers. If the reason cats are coming into your yard is because you’ve set up bird feeders, you’ll have to take them away or reposition them (if possible) so they aren’t such an appealing target. If you know who owns the feline intruder, perhaps you can have a tactful discussion about the situation.  If the appearance of outdoor cats is a real problem in your yard, you may have to consider fencing. There are companies that make cat-proof fencing. Many of my clients have also had success with motion-activated sprinklers.

Speaking of outdoors, if you allow your cat outside, that may be contributing to the spraying behavior. While some indoor/outdoor cats may restrict their marking to the outdoors, your cat may feel threatened by unfamiliar scents he encounters and might bring his spraying behavior inside as well.

Here are some additional guidelines for helping a sprayer:

  • Reduce household stress if possible (chaotic environment, erratic schedules, improper new pet introductions, etc)
  • increase vertical territory
  • Make sure your cat has safe areas to retreat such as hiding places, cat trees, cat beds
  • In a multicat environment make sure everyone has their own favorite perching spot
  • In a multicat environment increase the number of litter boxes and scatter them throughout the house so no one has to pass an opponent’s area in order to eliminate
  • Set up more than one feeding station so no one has to compete when you have more than one cat
  • If you think your cat is about to engage in spraying, distract him with a enticing sound to change his mindset from negative to positive (for example, roll a ping pong ball in the opposite direction)
  • Incorporate daily individual interactive playtime to help reduce anxiety and increase feelings of confidence and security
  • Increase environmental enrichment to create constructive and positive diversions
  • In some  multicat household cases, cats may need to be separated so a reintroduction can be done
  • If the cat is spraying a family member’s items, have that family member be the one who offers the meals and also have that person engage the cat in interactive play
  • If the cat is spraying a family member’s items, use a synthetic pheromone spray on some of the clothes to help the cat think he has facially rubbed those items
  • If spraying is done as a bonding behavior with a family member, increased playtime and environmental enrichment may help build confidence
  • Ease your cat through changes rather than force him to endure abrupt ones

Spraying Behavior is Complex

This article is just meant to provide a general road map for you. Your cat’s situation is unique so take time to carefully evaluate your cat’s environment and his behavior. The spraying behavior is a normal communication tool (yes, I understand it’s not one humans like very much) but with time and a solid game plan, you’ll hopefully be able to find a solution that works for both the cat and the human family members.

Seeking Professional Help

If you’re not having success with behavior modification, talk to your veterinarian about whether the cat may benefit from behavioral medication. If your cat is put on medication, keep in mind this is to be an adjunct to behavior modification.

Your veterinarian may also refer you to a veterinary behaviorist, certified applied animal behaviorist or a certified cat behavior consultant. A qualified professional can help in pinpointing the cause of the behavior and set up a customized behavior modification plan.

  1. What are some signs I can look for to be able to tell if its territorial marking or self soothing? I have a neutered male cat who I’ve seen spray and 5 other cats. We’ve had them all for a long Whatime and everyone seems to get along well. Then suddenly almost 2 years ago my one cat started spraying, indoors and out. There were no changes in our lives like a new cat or anything. He started acting aggresive towards a neighborhood cat around the same time too. I’ve tried feliway and giving him positive reinforcement when he’s around the other cats and being good incase he has a problem with them and I dont know it. I’m also making sure to clean up everything with an enzyme cleaner.
    We’re moving soon and I want to try to help him before we move because I know that will be a big stress and don’t want it to make him spray even more. How can I get this under control?

    I’ve bought your books and waiting for them in the mail but thought maybe someone can provide some tips while I’m waiting. Thanks for your time!

  2. I also forgot to add that he was checked out by our vet and he found nothing to medical causing him to spray and placed him on cat Prozac which did nothing to help with the spraying.

  3. Interestingly enough my (all neutered) male cats have sprayed less since we allowed this one male to travel outdoors (with claws). The other cats in the house never quite accepted him and with him venturing out of the house they all feel a little more secure. The cats inside the house are declawed. Could they feel threatened by the one because of the claws?

  4. i have a male cat that was a stray,i got him neutred and he new he was onto a good thing so he stayed around.i also have 2 female sister cats who give him a bit of a hard time but he seems well able and does seem to bring it on sometimes.he sprays in the house,is there anything i can do to stop him spraying?

  5. My male cat will not stop peeing on a 2 month old new bed!He should be ok with it by now? What’s up with that?

  6. This was a pretty helpful article. I am at my wit’s end with my 14 year old neutered male cat, Merlin. The spraying started around the time my crazy, aggressive kitten, Abomination grew into adulthood, however Merlin was treated for a urinary infection which probably exacerbated things. Now the infection is healed but he is perimeter spraying everywhere, all over both the front and back doors, in the laundry room, even in my bedroom where the kitten is not allowed (the older cat has 100% access to the bedroom through an electronic pet door that the kitten cannot get into.) The house reeks. For fourteen years we were that house where nobody knew we had a cat… now it’s obvious from first walking in the door. I’ve even steam-cleaned the rugs, it’s just pointless because he soils them all over again. He does it two feet in front of me, my presence is zero deterrent at all.

    I’ve spoken three times with the vet and she is convinced the spraying is due to outdoor cats, not the kitten. The cats are now both on Zoloft transdermal to calm them down, but it will be a few weeks before we see an effect, if any. I am truly stressed and have spent hundreds of dollars trying to fix the problem, including buying a new cat tree, the aforementioned very expensive electronic pet door, and adding a big litter box to the living room (where it all began.)

    I have days where I want to ship them both to Abu Dhabi, Garfield-style.

    I guess I just want to vent. At any rate, I’m going to try some of these behavioral tips to see if it helps at all. I’m encouraged by the idea that I haven’t ”tried everything” because it sure feels that way. I have a very flexible, open-ended schedule which means they don’t have a lot of routine either. I’m going to really try to work on that.

  7. i have two kittens, Oreo (cali) and Tiger(tabby),i think Oreo is the one who is spraying. how can i stop it my kitten oreo is only spray on ME!!

  8. I have a female cat that turned 1 on February 26,2018. When we lived in our 3 bedroom house she wasn’t marking/spraying anything. I have a male cat that is nutered and another female that’s older. Anyways my youngest cat goes into heat every other week but she pees inside of anything that is not the litter box (laundry baskets, bath tub, etc.) She has an appointment May 7th to be fixed. I don’t know what to do about her I’ve had her since she was born and she has never done this. My partner and I of almost a year moved to a 1 bedroom apt in March, but she didn’t start marking things til probably about April ish.she poops in the litter box but pees inside of everything else ( but not on the floor) like laundry baskets and the tub,I have tried disciplining her but she wont stop. Any ideas on what I should do? Please help I don’t want to have to get rid of her
