Cat sneezing is a common health concern that most pet owners will encounter at some point. While you may be familiar with the typical causes of cat sneezing, there’s one surprising reason that many pet parents often overlook. 

This article explores that hidden cause.

In addition to revealing a hidden cause of both indoor and outdoor cat sneezing, this article provides valuable insights, including effective home strategies and guidance on when to seek professional help for your cat’s health.

What Exactly is Sneezing in Cats?

Sneezing in cats is simply a sudden, forceful expulsion of air through the mouth and nose, often occurring unexpectedly. While it is generally harmless, many cat parents mistakenly assume that sneezing is a condition. It’s a clinical sign that can signal an underlying health issue.

A sneeze or two from your cat is usually nothing to worry about. However, if the sneezing becomes persistent or chronic, it may signal a more serious condition that requires professional care. In such cases, consulting your veterinarian or a pet homeopathy specialist is highly recommended.


What is “Reverse Sneezing” in Felines?

Reverse sneezing in cats is a reflex where they quickly draw air in through the nose, producing a distinctive honking or choking sound. During these episodes, cats often stand still with their necks extended, which can appear alarming to pet owners.

Occasional reverse sneezing in cats is usually harmless and doesn’t require medical attention. Cats are more likely to experience a regular sneeze than a reverse sneeze, which is less common. However, if these episodes become frequent or prolonged, it’s best to consult your veterinarian or a qualified pet homeopath to rule out any underlying health concerns.

The Surprising Cause of Cat Sneezing You Never Expected

As mentioned earlier, you may already have a list of possible causes for your cat’s sneezing in mind. However, did you know that dental issues can also be a surprising trigger for sneezing in felines? Let’s explore this connection further.

Dental disease in cats, including infections and inflammation, can sometimes extend from the mouth to the nasal passages, causing sneezing. Dental problems can lead to systemic inflammation, which, in turn, can lead to sneezing and respiratory issues.

Typical signs of dental problems include bad breath, drooling, and difficulty eating. Early detection and treatment can improve your cat’s comfort and prevent further health issues.

Because the tooth roots in a cat’s upper jaw are close to the nasal passages, dental problems, particularly abscesses, can often lead to respiratory symptoms like sneezing. Studies show that 50-90% of cats over four years old develop some form of dental disease, increasing the risk of complications. 

Timely veterinary care is crucial for managing dental problems in cats and preventing complications like sneezing and discomfort. Consistent dental check-ups and cleanings help maintain your cat’s oral health, reducing the risk of future issues. Regular consultations with a pet homeopathy expert are also helpful.

Exploring Other Key Causes of Feline Sneezing

Now that we’ve covered dental issues, let’s explore other possible causes of sneezing in cats. In this section, we’ll discuss allergies, respiratory infections, foreign objects, chemical irritants, nasal polyps and growths, Feline Herpesvirus (FHV), fungal infections, and intranasal vaccines.

Allergies

Even indoor cats can develop environmental allergies to dust, mold, and pollen that enter the home. These allergens can trigger sneezing, itchy skin, watery eyes, and coughing, making regular cleaning and air filtration essential for your cat’s comfort.

Food allergies in cats can trigger sneezing as the immune system reacts to certain ingredients. Other symptoms may include vomiting, diarrhea, and skin irritations, and an elimination diet can help identify the allergens causing these reactions.

Allergies in cats are more likely to cause skin irritation and itchiness than sneezing, though it can still occur in some cases. Common airborne allergens like mold, dust, perfume, smoke, and cleaning supplies may also trigger sneezing and discomfort.

Respiratory infections

Upper respiratory infections (URIs) frequently trigger sneezing in cats and can be caused by viruses, bacteria, or fungi. Common symptoms include sneezing, nasal discharge, coughing, and lethargy, with feline herpesvirus and calicivirus being the most prevalent viral culprits.

These infections are more common in young cats, especially those from shelters, and may require veterinary care or a consultation with a pet homeopathy specialist to ensure proper treatment.

Conversely, chronic respiratory conditions in cats, such as feline asthma and chronic bronchitis, can lead to frequent sneezing and require careful, ongoing management. Routine veterinary check-ups are essential for keeping these conditions under control and preventing further complications.

Viral infections can sometimes lead to secondary bacterial infections, like Bordetella, Mycoplasma, and Chlamydia, often indicated by yellow or green nasal or eye discharge. Other viral infections, such as feline herpesvirus (rhinotracheitis), Feline Immunodeficiency Virus (FIV), and feline leukemia, can also lead to sneezing in cats. 

Stress can exacerbate upper respiratory infection (URI) symptoms, making cats more vulnerable to complications. This is especially true for feline herpesvirus, where stress can increase the likelihood of symptom flare-ups and transmission.

Foreign objects

Cats are naturally curious and may accidentally inhale or ingest foreign objects, which can trigger sneezing. Common offenders include grass, dust particles, and small toys, but grass awns (foxtails) are especially problematic due to their ability to become lodged in the nasal passages.

Sudden and repetitive sneezing may signal that a foreign object is lodged in your cat’s nasal passages, requiring immediate attention. If the sneezing continues or your cat shows signs of distress, contacting your veterinarian promptly is the best course of action.

Chemical irritants

Household chemicals and cleaning products can irritate a cat’s respiratory system, often causing sneezing and discomfort. Common irritants include air fresheners, scented candles, certain types of litter, cigarette smoke, and perfume. To protect your cat, consider using pet-friendly products and ensuring proper ventilation in your home.

Nasal polyps and growths

Nasal polyps, which are non-cancerous growths, can obstruct airflow in cats and cause sneezing, nasal discharge, and breathing difficulties. In some cases, growths or tumors inside the nose may also trigger sneezing, occasionally accompanied by bloody discharge. To confirm a diagnosis, procedures like rhinoscopy or biopsy may be required.

Feline Herpesvirus (FHV)

Feline Herpesvirus (FHV) is a widespread viral infection in cats that commonly causes sneezing, nasal discharge, and eye irritation. Cats infected with FHV may experience recurring episodes, especially during times of stress

Although there is no cure, reducing stress and supporting the immune system can help manage flare-ups effectively. Fortunately, FHV is not contagious to humans.

Fungal infections

Fungal infections in cats are less common but can still cause sneezing and other respiratory issues. Cryptococcus is one of the most common fungal culprits, and diagnosing these infections may require blood tests, rhinoscopy, or biopsy. Treatment typically involves several months of oral antifungal medication to clear the infection.

Intranasal vaccines

Sneezing is a common side effect that can occur 4-7 days after an intranasal vaccine in cats, typically lasting only a few days. This mild reaction is usually harmless and resolves without the need for treatment.

10 Easy Home Hacks to Relieve Cat Sneezing Fast

If you’re like most cat parents, your first instinct might be to reach for conventional medications when your cat starts sneezing. However, there are also effective home hacks that can help manage this issue. These include:

#1. Regular monitoring of your cat’s clinical signs is essential.

Monitoring your cat’s symptoms closely can help identify health concerns before they become serious. Watch for changes in sneezing, appetite, or energy levels to ensure prompt care if needed.

#2. Take note of any triggers or patterns of your cat’s sneezing.

Identifying patterns or triggers behind your cat’s sneezing can help uncover potential causes. Pay attention to whether symptoms occur after cleaning, using the litter box, or exposure to other environmental factors.

#3. Create a calm, secure environment where your cat feels safe and comfortable.

Providing a comfortable, low-stress environment can help minimize or prevent sneezing in cats. Reducing stress through quiet spaces, cozy bedding, and minimal disruptions supports your cat’s respiratory health.

#4. Ensure your cat is eating and drinking regularly to maintain optimal health and hydration.

Monitoring your cat’s eating and drinking habits is essential for detecting potential health issues early. Any noticeable changes in appetite or water intake may signal an underlying problem that requires veterinary attention or pet homeopathy consultation.

#5. Keep your cat’s face clean to prevent irritation and reduce the risk of infections.

Gently clean your cat’s face with a warm, moist cloth to remove any discharge and prevent irritation. Regular cleaning helps maintain your cat’s comfort and reduces the risk of infections.

#6. A humidifier can help reduce sneezing and keep your cat more comfortable.

Using a humidifier can help keep your cat’s nasal passages moist, reducing the likelihood of sneezing and respiratory discomfort. Maintaining proper humidity levels is especially beneficial for cats prone to respiratory issues.

#7. Eliminate potential irritants from your cat’s surroundings to create a healthier, more comfortable space.

Eliminating potential irritants such as air fresheners, strong perfumes, dusty litter, and harsh cleaning products can help reduce sneezing and respiratory discomfort in cats. Creating a cleaner, allergen-free environment promotes better respiratory health and overall well-being.

#8. Avoid trying to remove foreign objects from your cat’s nose, as this may lead to injury.

Avoid attempting to remove any suspected foreign object from your cat’s nose, as this can cause injury or worsen the situation. Instead, seek prompt veterinary care to ensure safe and effective removal.

#9. Capture a video of your cat sneezing.

Capturing a video of your cat sneezing may seem simple, but it can provide valuable information for your veterinarian or pet homeopathy expert. This helps them assess the situation more accurately and recommend the best action.

#10. Consider using premium natural products to support your cat’s respiratory health.

If your cat or small pet is showing signs of a respiratory virus, like sneezing, nasal congestion, or clear ocular discharge, BREATHE-EZ (CLEAR) offers gentle, natural support.

Specially formulated for respiratory support, BREATHE-EZ (CLEAR) helps reduce symptoms, such as sneezing and nasal blockage, clear nasal and ocular discharge, irritated nostrils, difficulty breathing, and promotes overall comfort.

As emphasized earlier, occasional sneezing in cats is usually nothing to worry about. However, it’s best to seek veterinary care if any of the following arise:

  • Sneezing that persists for more than a couple of days.
  • Frequent or recurring sneezing that doesn’t improve.
  • Continuous, uncontrollable sneezing episodes.
  • No improvement after trying home remedies.
  • Sneezing accompanied by blood.
  • Signs of pain, discomfort, or distress.

Additionally, sneezing that occurs alongside other signs of health concerns should not be ignored. Be sure to contact your veterinarian if you notice any of the following symptoms:

  • Eye discharge, swelling, or the presence of ulcers.
  • Loss of appetite or a noticeable decrease in food intake.
  • Elevated body temperature or fever.
  • Sudden changes in behavior or mood.
  • Bad breath may indicate dental problems.
  • Coughing, wheezing, or labored breathing.
  • Difficulty breathing or heavy panting.
  • Unexplained weight loss.
  • Unusual lethargy or persistent fatigue.
  • Nasal discharge, especially if thick, discolored (yellow, green, brown), or bloody.
  • Frequent pawing at the face or mouth.
  • Excessive drooling or salivation.

How Do Vets Diagnose Feline Sneezing?

A veterinarian will begin by performing a thorough physical exam, which includes checking your cat’s dental health. If necessary, diagnostic tests such as swabs from the mouth, throat, eyes, or nose may be taken for lab analysis. Blood and urine tests may also be conducted to identify underlying health issues.

If your cat continues to sneeze frequently, your veterinarian may suggest additional diagnostic procedures during the checkup. These may include imaging tests like X-rays or CT scans, a rhinoscopy to examine the nasal passages, or a nasal biopsy to analyze tissue samples. 

In some cases, a nasal lavage might also be performed to flush the nasal passages and gather samples for further evaluation.

What are the Standard Treatments for Cat Sneezing?

Various conventional treatment options are available to effectively treat and manage sneezing in cats. However, these may vary depending on the underlying cause. These typically include:

  • Dental treatment, including cleanings and extractions, is used to manage dental disease.
  • Allergy management through specialized diets, immunotherapy, or medication.
  • NSAIDs to reduce inflammation and discomfort.
  • Use of humidifiers or nebulizers to maintain moisture in the air.
  • Surgery is required in rare cases to remove foreign bodies, polyps, or tumors.
  • Antifungal medications are used to treat fungal infections.
  • Antibiotics are used to address bacterial infections.
  • Antihistamines or steroids to manage allergies and inflammation.
  • Nasal lavage to temporarily relieve symptoms and clear nasal passages.
  • L-Lysine supplementation to help manage feline herpesvirus.
  • Antiviral medications, such as famciclovir, are used for viral infections like herpes.
  • Decongestants to ease nasal congestion and improve breathing.

For chronic cases, the goal of treatment is typically to manage and lessen the frequency and severity of symptoms, rather than provide a complete cure. With ongoing, consistent care, your cat’s condition can remain well-controlled, enhancing their overall quality of life.

Adhering closely to your veterinarian’s recommendations is crucial for ensuring the best possible outcomes for your cat’s health. Vaccinations, particularly against feline herpesvirus and calicivirus, are vital in preventing respiratory infections and minimizing the risk of complications.

Keeping your cat’s vaccinations up to date is essential for protecting them from common and potentially serious illnesses. Regular immunizations help safeguard their health and reduce the risk of preventable diseases.
