If you have noticed stray cats spraying outside your house, you may wonder why this behavior is occurring and what can be done about it. The truth is that there are various reasons why cats spray, and each situation needs to be examined on its own merits. In this blog post, we will look at some of the possible causes of stray cat spraying and tell you how to stop this unwanted behavior.


Why are stray cats spraying outside my house?


Stray cats spraying outside your house may be an unwelcome surprise, but they might be doing so for a few reasons.

The leading cause is territorial marking; stray cats are just trying to let others know that the area around your home is already taken.

The smell warns other cats that they should look for food and safe nesting spots elsewhere.

In addition, unspayed female cats will spray before coming into heat as part of their mating cycle.

Furthermore, sick or injured cats may spray due to distress or pain. If you are dealing with this problem, it’s best to contact your local animal control service for assistance in trapping the cat from your property humanely.


Territorial Spraying


Stray cats often mark their territory with a type of ‘spraying.’ This is done by backing up to an object, such as a house, fence, or tree, and releasing an aromatic scent from the anal glands.

For feral cats, in particular, this action serves two purposes:

First, to alert other cats that passing through is not allowed;

Secondly, to promote the claim of ownership over the area surrounding your house.

However, this territorial behavior can be disruptive for humans living nearby.

Understanding why cats engage in spraying behavior and learning to discourage it may help you keep your home barriers urine-free and maintain a good relationship with stray cats in your area.


Stress-Related Spraying


Stray cats spraying outside of a house is usually because they feel threatened or intimidated by their environment.

This type of stress-related spraying is the cat’s way of protecting its territory and marking where it feels safe.

Strange animals may cause high anxiety levels in cats in the area, changes in routine, loud noises, and unfamiliar smells.

While this behavior can seem undesirable to humans, it is a normal reaction for cats. It can be managed by creating a safe space for them away from other animals or any potentially stressful or dangerous situations.

Keeping your property and gardens clean of attractants like food scraps can also help reduce territorial behavior in strays.


Medical Issues


Stray cats spraying outside of a house can be a frustrating experience.

Urine marking, as it is called, is mainly done by unsterilized male cats to claim their territory. However, it may also be done out of fear or anxiety if they feel threatened by other cats on the premises.

Unfortunately, medical issues may sometimes be the cause of this behavior.

Cats suffering from urinary tract infections or blockages often feel the need to urinate more frequently, leading them to spray around your property.

These cats will likely require veterinary assistance to resolve their problems and resolve their inappropriate urination.


How to Stop Stray Cats from Spraying Outside Your Home


Unwanted cats can cause several issues, from digging in your garden to spraying outside your house. While it’s not uncommon for cats to spray, it can be annoying and unhygienic. Fortunately, there are ways to discourage unwanted cats from spraying outside your home.


 How to Stop Stray Cats from Spraying Outside Your Home


If you’re dealing with cats spraying outside your home, the first step is understanding why they may be doing it.

Stray cats spray to mark their territory and show dominance over other animals who may be in the area. To prevent stray cats from spraying in your yard, it’s essential to remove potential food and shelter sources so they do not feel comfortable in the area.

Deterrents like motion-activated sprinklers, citrus or ammonia-based sprays, pet urine-repellent granules, and citronella candles may also help deter them from marking your property as their own.

Ultimately, reducing the cat population will go the furthest to minimize instances of cats spraying outdoors; consult a local animal cruelty organization for more information on humane spay/neuter programs that can help manage cat populations safely.


Identifying the Cat or Cats


The first step is figuring out which cat or cats are responsible for the spraying. Unfortunately, this can be difficult if the cats are strays, as they may not have any identifying features or tags.

However, if you identify them (for example, by recognizing their fur color or markings), you can take steps to discourage them from returning.


Discouraging Spraying


You can do a few things to discourage stray cats from spraying outside your house.

The most effective way is using deterrents such as motion-activated sprinklers or sound machines that will startle the cat when they come close to your property.

If you want a more humane solution, there are also unique scents you can buy that will make the area smell unpleasant to the cat and discourage them from returning.

You should also ensure that there aren’t any food sources near your property, as this could attract the cats in the first place.


Keeping Your Own Pets Safe


If you own a pet cat yourself, you must keep them safe from any strays in the area.

Ensure all doors and windows in your house are closed and secure so they don’t wander off without supervision.

If possible, keep an eye on them outside so they don’t come into contact with other cats in the area who could potentially harm them. Vaccinating them against common illnesses is also wise so they don’t catch anything if they encounter a stray cat outdoors.



Spraying is an issue for many people living near stray cats’ colonies. Therefore, you must proactively discourage cats from marking their territory near your home and property.

  • Start by avoiding direct contact with the cats–incredibly aggressive behavior–as this may worsen the problem over time.


  • Secondly, try using materials with strong scents that may be unpleasant to cats, such as citrus peels or coffee grounds, in areas where they tend to congregate.


  • Thirdly, build physical barriers around areas where you don’t want the cats coming and limit access to food sources; without food or shelter, there is less incentive for cats to hang around your property.


  • Finally, understanding why feral cats are spraying in the first place can help to inform how you respond and prevent future incidents.

Addressing these issues directly and consistently taking steps to diminish them will decrease the chance of stray cat spraying outside your home.
