Cats sneeze for many reasons. Some are harmless. Others need attention. This guide explains common causes. It covers symptoms to watch. You will learn when to visit a vet. We also share home tips.
Common Causes of Cat Sneezing
Cats sneeze to clear their nose. A single sneeze often means nothing. Frequent sneezing points to issues.
Upper Respiratory Infections
These are like colds in cats. Viruses cause most cases. Feline herpesvirus and calicivirus are common. Bacteria can join in. Fungal infections happen too. Kittens and older cats get hit harder.
Allergens and Irritants
Dust, pollen, or smoke can bother a cat’s nose. Cleaning products or perfumes trigger sneezes. Allergies are less common in cats than people. But they do occur.
Foreign Objects
Grass, hair, or lint can get stuck. The cat sneezes to push it out. This happens more with curious cats.
Dental Problems
Bad teeth lead to infections. These spread to the sinuses. Sneezing follows. Look for bad breath too.
Other Issues
Nasal polyps or tumors are rare. They block airways. Vaccines can cause short-term sneezing. Chronic rhinitis inflames the nose long-term.

Symptoms to Watch For
Sneezing alone may be fine. Pair it with other signs for concern.
- Nasal discharge. Clear is mild. Yellow or green means infection. Blood is serious.
- Eye problems. Watery eyes or swelling.
- Coughing or wheezing.
- Low energy or no appetite. Link this to our post on how long can cats go without eating.
- Fever or bad coat.
- Pawing at the face.
