Why Cats Sneeze
An occasional sneeze in a cat is normal and no real cause for alarm. Just as in humans, sneezing in cats is an explosive release of air through the nose and mouth - often the body’s response to irritants in the nasal passages. Sometimes, excitement or movement can bring on sneezing in cats.
However, if your cat’s sneezing won’t go away, or if other symptoms have cropped up along with sneezing, you may need to check with your veterinarian to see if treatment is needed.
Causes of Sneezing
If your cat is sneezing a lot, your veterinarian may initially suspect a cause based on a review of your cat’s symptoms. One of the main causes of sneezing is infection. In some cases, the vet may take a swab from the mouth, throat, eyes, or nose and send it to a lab to confirm an infection. Inhaled irritants or allergens are other common causes of sneezing in cats.
Viral, bacterial, or fungal infections. If you’ve got a sneezing cat, chances are good the cat has an upper respiratory infection. Similar to colds in humans, these infections are more common in young cats, especially in those coming from animal shelters. Many of these infections can be prevented with early and complete vaccinations.
Viral infections that most commonly cause sneezing in cats are:
These infections may make your cat more likely to develop other respiratory problems that can exacerbate sneezing. For example, a cat with herpes may also develop a secondary bacterial infection. These are often treatable with antibiotics.
A wide range of other infections may also lead to sneezing. They include:
Inhaled irritants or allergens. If your cat only sneezes once in a while, something may simply be irritating the nasal passages. Look for patterns in your cat’s sneezing. Does it occur after you’ve lit the candles at the dinner table? After your cat leaves the litter box? After you’ve cleaned the house?
In cats, allergies are a less common cause of sneezing than in humans. If sneezing is related to allergies, sometimes itchy skin is also present.
Other potential causes of sneezing. A variety of other factors may contribute to sneezing in cats. For example, it’s common for cats to experience sneezing within four to seven days of receiving an intranasal vaccine. This sneezing lasts for no more than several days. Cats may also sneeze to try to dislodge a blockage in their nasal passages. An infection or inflammation of a tooth root may cause drainage into the sinuses and may also cause sneezing. In very rare cases, sneezing in cats can be a sign of cancer.
