It isn’t just us humans who have allergies.
Even cats can.
While the reason may vary from one species to another, as a cat owner, it is really important that we understand the reason why.
Since cats can’t speak for themselves (sometimes we wish they could), we need to be extra mindful of them.
We should learn to differentiate between the different kinds of sneezes.
Thus we bring to you a meticulous and detailed article on the probable reasons why cats sneeze and what you can do to avoid it.
1. Upper Respiratory Infections (URIs)
One of the most common reasons for frequent sneezing in cats is an upper respiratory infection. These are typically viral, bacterial, or fungal in nature—caused by agents like feline herpesvirus, calicivirus, or chlamydia.
Cats in shelters or multi-cat households are particularly vulnerable due to the ease of transmission. You might also notice symptoms like nasal discharge, watery eyes, coughing, or a lack of appetite.
These infections can become chronic, especially herpesvirus, which stays in a cat’s system for life and can flare up with stress. In such cases, sneezing is often a daily or frequent occurrence.
2. Allergies
Though less common than in humans, cats can suffer from environmental allergies. Pollen, dust mites, mold, cigarette smoke, perfumes, or even certain cleaning products can irritate their nasal passages.
Sneezing caused by allergies may occur seasonally (like springtime) or after exposure to specific triggers. You may also see itchy skin, watery eyes, or respiratory irritation.
It’s important to observe your cat’s surroundings to identify patterns or triggers. Keeping your home free of strong scents and allergens can significantly help.

3. Foreign Bodies in the Nose
If your cat suddenly starts sneezing persistently, it might be due to a foreign object lodged in their nasal passages—like a blade of grass, dust, or a seed.
This can cause irritation, leading to sneezing fits as the body tries to expel the object. You might notice your cat pawing at their nose or showing discomfort.
In some cases, a vet may need to use special tools to inspect and remove the object safely. Never attempt to do this yourself as it could injure your cat’s nasal tissues.
4. Dental Problems
Believe it or not, dental disease can cause sneezing in cats. Infections in the teeth or gums, particularly in the upper jaw, can affect the sinuses due to how close the tooth roots are to the nasal cavity.
A bad tooth or oral abscess might lead to a chronic nasal infection or discharge. Signs include bad breath, drooling, loss of appetite, and visible inflammation in the mouth.
A dental exam and possible tooth extraction might be necessary to resolve the issue—and the sneezing.
5. Nasal Polyps or Tumors
Chronic sneezing in cats can sometimes be caused by growths in the nasal passages, like polyps or, more rarely, tumors. Nasal polyps are benign but can obstruct airflow and cause inflammation.
These often result in noisy breathing, nasal discharge (possibly bloody), and frequent sneezing. Tumors are more likely in older cats and may come with weight loss or facial swelling.
A vet may recommend imaging (like X-rays or CT scans) to diagnose these issues and determine treatment—whether surgical removal or other interventions.
6. Fungal Infections
Fungal infections like Cryptococcus can also lead to ongoing sneezing. This type of infection often comes from inhaling fungal spores found in soil or bird droppings.
Besides sneezing, symptoms may include nasal swelling, discharge, or lesions around the nose. Fungal infections typically require a long course of antifungal medications and close veterinary monitoring.
Though less common, they should not be overlooked—especially in outdoor cats or those with weakened immune systems.
7. Irritants in the Environment
Strong smells and chemicals can easily trigger sneezing in cats. Household products like scented candles, air fresheners, bleach, ammonia-based cleaners, or even cat litter with dust can irritate their sensitive noses.
If sneezing happens shortly after cleaning or changing products in the house, it’s likely environmental. Opting for unscented or pet-safe alternatives can reduce the problem significantly. Keeping windows open for ventilation when cleaning can also help.
8. Breed-Specific Issues
Some cat breeds, particularly flat-faced (brachycephalic) cats like Persians, Himalayans, and Exotic Shorthairs, are more prone to sneezing due to their narrow nasal passages and compressed facial structure.
These breeds may sneeze more frequently than others simply because airflow is more restricted. In these cases, the sneezing may not indicate illness but rather a structural predisposition. However, they are also more vulnerable to respiratory infections, so any changes should still be monitored.
9. Dry Air or Sudden Temperature Changes
Dry, heated air in winter or sudden cold drafts can dry out or irritate your cat’s nasal lining, leading to sneezing. Cats exposed to air conditioners, heaters, or fans blowing directly on them may show symptoms like sneezing or nasal dryness.
Running a humidifier or placing water bowls near radiators can improve air moisture and soothe their sinuses. This is especially useful in dry or seasonal climates.
10. Vaccination Side Effects
In some cases, sneezing is a mild side effect of recent vaccinations, especially if your cat received intranasal vaccines (administered through the nose). This reaction usually resolves within a few days and doesn’t require treatment.
If your cat starts sneezing after a vet visit and shows no other symptoms, it may just be a temporary effect of the vaccine. However, if it persists or is accompanied by other signs, call your vet for advice.
What Can You Do to Help or Prevent Sneezing in Cats?
While occasional sneezing isn’t a concern, chronic or frequent sneezing should be taken seriously. Here are a few things you can do to manage or prevent the issue:
-
Keep your home clean but scent-free: Avoid using air fresheners, incense, and strong-smelling cleaners. Choose pet-safe, fragrance-free options.
-
Use low-dust or unscented litter: This reduces inhaled particles that may irritate your cat’s nose.
-
Boost your cat’s immunity: Provide a healthy diet, reduce stress, and stay current with vaccinations.
-
Maintain dental hygiene: Regular dental check-ups and cleanings can prevent oral infections that spread to nasal passages.
-
Control allergens: Dust regularly, vacuum with HEPA filters, and avoid smoking indoors.
-
Visit the vet for chronic sneezing: If symptoms last more than a few days or include discharge, lethargy, or appetite loss, a professional exam is crucial.
-
Use a humidifier: Especially in winter, this helps keep your cat’s nasal passages moist and less prone to irritation.
