There are many potential causes of sneezing in cats and kittens. The most common categories are upper respiratory infections, rhinitis or sinusitis, nasopharyngeal polyps, foreign bodies, parasites, trauma, and neoplasia. Keep reading to learn more about these possible causes and how your cat’s symptoms can be diagnosed and treated.

Sneezing in cats is common, often considered normal, and may even sound cute at times. It’s usually not a cause for concern especially if it occurs sparingly. However, frequent sneezing can be an indication of a health problem, and appropriate veterinary attention may be needed to assess the underlying cause.
Sneezing is a cat’s natural way to clear its nasal cavity of any foreign objects or irritants. When they accidentally inhale dust, pollen, or other objects that are small enough to enter their nostrils and get trapped within the nasal passages, sneezing is the body’s way to attempt to remove them.
For the most part, sneezing is a very effective means for a cat’s body to remove any inhaled irritants and protect the respiratory tract. But in cases where sneezing is persistent, excessive, and causes nasal discharge such as mucus and blood, a proper diagnosis is needed to control the animal’s sneezing fits.
Simple Irritation
Inhalation of strong scents or environmental irritants is the most common cause of sneezing in cats. These animals can have sensitive olfactory senses and can detect even the most subtle scent in the environment.
They react to strong scents similarly to us, and while these are usually not strong enough to cause a serious inflammatory or allergic reaction, it’s enough to irritate the lining of the cat’s nasal passages and cause sneezing. For most cases, the sneezing usually stops as soon as the exposure has been eliminated, and no medications are usually needed.

Periodontal (Dental) Disease
The dental architecture and nasal passages of a cat are closely associated with each other. Some dental roots in the maxilla (upper jaw), particularly the premolars and molars, have roots that extend up to the border of the nasal passages. Infections in the roots of these teeth can leak into the nasal passages and cause sneezing in cats.
A thorough physical exam and diagnostic tests such as blood work and radiographs (x-rays) can help determine if the cause of sneezing is due to a pre-existing periodontal disease. For these cases, treating periodontal disease is the only way to control sneezing. Medications directed to control sneezing and inflammation are usually ineffective since the primary problem is originating elsewhere.
Diagnosis of sneezing in cats can be very simple or may be complicated, depending on the underlying cause. Common diagnostic steps include:
Treatment for your cat’s sneezing is based on clinical signs and diagnosis. This may include:
Please note: If there is no response to treatment or treatment is unsuccessful, sometimes surgery (sinusotomy or rhinotomy), lavage, and biopsy are necessary to reestablish a definitive diagnosis.
NOTE! Never give your cat any type of human medication unless instructed to do so by your veterinarian! Many types of pain medications, fever reducers, and decongestants contain substances that are toxic and potentially life-threatening to cats.
