No verifiable September 2026 breakthrough has changed how cat spraying should be handled. The closest documented 2026 development is updated caregiver guidance that places spraying within a broader medical and behavioral assessment. Urine spraying is scent marking, usually involving urine deposited on a vertical surface. It differs from other house-soiling, which may stem from illness, litter-box problems, environmental stress, or conflict between cats.

What actually changed in 2026?
The main development is a clearer emphasis on evaluating the whole cat and household. The Feline Veterinary Medical Association's 2026 caregiver update does not announce a new treatment, product approval, or rule. Instead, the guidance discourages treating every indoor urination problem as a behavior issue.
FelineVMA advises a physical examination and urinalysis for every cat that newly begins house-soiling because conditions such as cystitis, arthritis, kidney disease, diabetes, and infection can contribute to it in its 2026 house-soiling update. This matters because a deterrent or litter-box change cannot resolve an untreated medical cause. It also prevents owners from blaming a cat for behavior the animal may not be able to control.
Is it spraying or another urinary problem?
Spraying commonly occurs while a cat stands, raises its tail, and directs a relatively small amount of urine toward a vertical object. Other house-soiling may involve squatting and leaving a larger amount on a horizontal surface. That distinction is useful but not diagnostic.
According to the AAFP/ISFM guidelines, spraying serves a communication function, while inappropriate urination can reflect medical, environmental, social, or litter-box causes that require different responses. Watch for signs that make prompt veterinary assessment especially important: These signs may occur with feline idiopathic cystitis, a fluctuating bladder condition associated with stress and diet changes. They should not be managed solely with behavior remedies.
- Frequent attempts to urinate
- Difficulty passing urine
- Apparent pain during urination
- Blood in the urine
- A sudden change in urinary habits
Which cats and households need closer attention?
Intact cats may mark for sexual reasons. Spaying or neutering remains the central physiological measure for sexually related marking, although it does not address every medical, environmental, or social trigger. Cats outside windows or doors can prompt indoor marking. An unfamiliar cat entering through a cat door may create an even more direct territorial challenge.
Blocking the view, controlling cat-door access, or separating the indoor cat from the trigger can help clarify the pattern. Multi-cat homes also require careful observation. FelineVMA's 2024 intercat-tension guidance says tension is common, can be subtle, and can arise in a home with only two cats; introducing a new cat is the most frequent starting point identified by the guidelines. Look beyond obvious fights. One cat may stare at another, guard a hallway, block a litter box, or repeatedly displace a housemate from resting and feeding areas.
What should owners do now?
Start with veterinary evaluation when the behavior is new, sudden, or accompanied by urinary symptoms. Then reduce competition and make essential resources easy to reach.
If the cat is avoiding a particular box, examine its location and accessibility rather than assuming stubbornness. Pain, fear, or another cat's presence may make an otherwise clean box difficult to use.
- Provide separate, accessible litter boxes in locations where another cat cannot trap or block the user.
- Reduce exposure to outdoor cats and prevent unfamiliar animals from entering.
- Spread food, water, resting places, hiding spots, and play opportunities through the home.
- Avoid shouting, spraying water, or other punishment, which can increase distress and worsen unwanted behavior.
- Record when and where incidents occur to reveal links with visitors, household changes, outdoor animals, or cat-to-cat encounters.
How do you prevent repeat marking?
Odor control is part of treatment because residual scent can draw a cat back to the same place. Locate affected areas with a UV light when necessary, clean them frequently with an enzyme-based product, and avoid ammonia cleaners. After cleaning, a synthetic pheromone product may be worth considering as part of a wider plan.
It should not replace medical assessment, adequate litter boxes, or action on household conflict. Evidence also has limits. The AAFP/ISFM guidelines note that house-soiling recommendations combine research findings with clinical experience where studies are lacking, and individual cases may have several causes. Persistent cases may require referral to a veterinary behaviorist or internist.
