Why Your Cat Keeps Sneezing: Common Causes Explained

Cats sneeze for a myriad of reasons, ranging from benign to potentially serious health concerns. Understanding why your feline friend keeps sneezing is crucial for ensuring they remain healthy and happy. Just like humans, cats can sneeze due to irritants, infections, or allergies, but distinguishing between these causes can be perplexing for pet owners. In this comprehensive guide, we’ll explore the common causes behind your cat’s sneezing, providing insight into when it’s a minor issue and when it might be time to seek veterinary intervention.


One of the most frequent reasons for a cat sneezing is exposure to various irritants. Dust, pollen, smoke, and even strong perfumes can trigger a sneeze reflex in your cat. This type of sneezing is usually sporadic and doesn’t indicate a severe health issue. However, reducing exposure to these irritants can help limit the frequency of these sneezing episodes.


Viral, bacterial, and fungal infections can also result in your cat sneezing. Among these, the feline herpesvirus and calicivirus are notorious for causing upper respiratory infections that lead to sneezing, conjunctivitis, and nasal discharge. Bacterial infections may follow these viral infections, complicating the condition. If your cat’s sneezing is accompanied by other symptoms, such as lethargy, reduced appetite, or discharge from the eyes or nose, it’s essential to visit a veterinarian for a diagnosis and treatment plan.


Like humans, cats can suffer from allergies that induce sneezing. Common allergens include pollen, mold, dust mites, and certain foods. If your cat seems to sneeze more during certain seasons or after being in specific environments, allergies might be the culprit. An animal allergist can perform tests to identify specific allergens, and treatment typically involves managing exposure to the allergen and possibly administering antihistamines.

Foreign Bodies

A sneeze can also be a response to something stuck in your cat’s nasal passages. Curious cats who sniff around small objects might accidentally inhale something, leading to persistent sneezing as their body tries to expel the foreign object. In such cases, veterinary intervention might be necessary to remove the object and prevent any potential infection.

Dental Issues

It might be surprising to learn that dental issues can lead to sneezing in cats. Issues like tooth abscesses can cause swelling and inflammation that may affect the nasal passages, triggering sneezes. Regular dental check-ups and addressing dental issues promptly can prevent this issue.

When to Worry

Occasional sneezing in cats is not usually a cause for concern. However, if your cat’s sneezing is persistent and accompanied by other symptoms like a runny nose, eye discharge, lethargy, or a decrease in appetite, it’s time to visit the vet. These could be signs of a more severe condition that requires medical attention.

Preventing Sneezing in Cats

While it’s impossible to prevent all causes of sneezing, maintaining a clean living environment, avoiding known irritants, and ensuring your cat is up-to-date on vaccines can help minimize the risk. Regular veterinary check-ups also play a vital role in identifying and treating potential health issues early.

In conclusion, while sneezing can be a normal reflex action for cats, persistent or severe sneezing warrants further investigation. By understanding the common causes and knowing when to seek professional advice, you can ensure your feline friend stays as healthy and comfortable as possible.

FAQs About Cat Sneezing

How do I distinguish between a simple sneeze and a sign of a more serious condition in my cat?

To differentiate between a harmless sneeze and a potential health issue, observe the frequency and duration of the sneezing, as well as the presence of other symptoms. Occasional sneezing is typically not a concern, but if the sneezing is persistent, occurs in bouts, or is accompanied by nasal discharge, eye discharge, lethargy, or appetite loss, it could indicate an underlying health problem. In such cases, a veterinary consultation is essential.

Can second-hand smoke from cigarettes harm my cat and cause sneezing?

Yes, second-hand smoke is harmful to pets, including cats, and can indeed cause sneezing, along with more severe respiratory issues. Tobacco smoke can lead to chronic irritation of the airways, increasing the risk of bronchitis and even lung cancer. Reducing or eliminating exposure to smoke is crucial for your cat’s health.

Are there effective treatments for cats with allergies?

Treating allergies in cats involves managing exposure to allergens and, in some cases, administering medication. The first step is identifying the allergen through tests by an animal allergist. Treatment strategies may include changes in the cat’s environment, special diets, antihistamines, or steroid treatments to control symptoms. Consultation with a veterinarian is essential to determine the most appropriate approach for your cat.

How can dental issues be related to sneezing in cats?

Dental issues can lead to sneezing in cats due to the close proximity of the nasal passages to the teeth. Problems such as tooth abscesses or gum disease can cause inflammation or infection that affects the nasal tissues, leading to sneezing. Regular dental check-ups and prompt treatment of dental issues are important to prevent this problem.

What steps can I take at home to reduce my cat’s sneezing?

To reduce sneezing caused by irritants or allergies, maintain a clean living environment by regularly vacuuming and dusting. Avoid smoking indoors and minimize the use of strong perfumes or cleaning agents that could irritate your cat’s respiratory system. If allergies are the cause, try to identify and limit exposure to the specific allergen, and discuss potential dietary changes with your veterinarian. For health-based causes like infections or dental issues, professional veterinary treatment is necessary.

Can certain breeds of cats be more prone to sneezing?

While any cat can experience sneezing episodes, some breeds are more predisposed to conditions that might increase sneezing frequency. For example, brachycephalic breeds like Persians, with their shortened nasal passages, may be more susceptible to respiratory issues that cause sneezing. Similarly, breeds known for dental issues might also experience related sneezing. Consultation with a veterinarian can provide guidance tailored to your breed’s specific needs.

Is vaccination effective in preventing respiratory infections that cause sneezing in cats?

Vaccinations can significantly reduce the risk of feline upper respiratory infections, such as those caused by the feline herpesvirus and calicivirus, which are common reasons behind sneezing. Regular vaccinations are an essential part of preventive health care, helping protect cats from several contagious diseases. Discuss with your veterinarian the most appropriate vaccination schedule for your cat.

When should I seek emergency care for my sneezing cat?

Emergency care is warranted if your cat’s sneezing is accompanied by other severe symptoms such as difficulty breathing, significant nasal or eye discharge, profuse bleeding from the nose, unresponsiveness, or any sign of pain and distress. These symptoms could indicate a serious health issue requiring immediate attention. It’s better to err on the side of caution and consult with a veterinarian as soon as possible in such situations.

By understanding your cat’s sneezing and recognizing the signs that indicate a need for professional help, you can better ensure the health and well-being of your beloved feline companion. Always remember, when in doubt, a visit to the vet can provide peace of mind and necessary care for your pet.
