Have you ever noticed your cat is constantly sneezing at times? Usually, it’s because something is tickling its nose—pollen, dust, or it may be just fur. So don't be alarmed; cats' sneezing is a way to stay healthy and remove stuff that doesn't belong in their noses.

But just how much sneezing is considered normal? Knowing the typical triggers of cat sneezing can help you understand what a regular sneeze is—and when you should actually begin to worry. 

So, if the question “Why is my cat sneezing so much?” has been constantly bugging you, stay here to see our list of 7 most common triggers for cat sneezing constantly.

What Causes Cats to Sneeze?

1. Innocuous Tickling Sensations

It's a pretty known fact that animals have more sensitive noses than humans. They can detect even the smallest particles in their surroundings, including dust or pollen that can stimulate your cat's nasal passages. This is the primary reason you often catch them sneezing—little things tickle their sensitive boops! Think of it as something similar to when we have an itchy spot; our first instinct is to scratch it, right? When they come in contact with a feline's sensitive nasal airways, it triggers a sneeze reflex. But don't worry; this is just a way for them to protect their respiratory system from potential irritants!

2. Respiratory Infections

Sneezing in cats may also mean an underlying respiratory infection, which is usually caused by viruses like herpes and calicivirus, or bacteria such as Mycoplasma. Some fungal infections can also inflame your cat's nasal passages, triggering sneezing fits.

But how do you know if some constant sneezing is already a sign of infection? Well, this comes with other symptoms: coughing and excessive tearing or eye discharge. If you do spot these signs, be sure to address these issues promptly to avoid further complications.

3. Irritating Chemical Substances

Got some general cleaning around the house done? If your pet feline seems to be in a sneezing fit, this may be due to common household irritants like air fresheners, perfumes, or everyday cleaning materials. 



It's important to be wary of how household cleaners and chemicals release strong fumes that may irritate your furbaby's respiratory system. The solution? Get pet-friendly and non-toxic cleaning supplies, ensure proper home ventilation, and minimize exposure to strong odors and allergens whenever possible. Keep in mind that your cat isn’t immune to cigarette smoke, so this may also be a factor.

4. Nasal Foreign Bodies

No, the phrase "Curiosity killed the cat" isn't just some random saying—most of the time, a cat's natural instinct to explore does get it into some deep trouble! For example, pieces of grass can accidentally get stuck inside their nose, so they sneeze to expel the foreign object. We can't blame them; it must be so itchy and painful!



However, there's a risk of potential infection in your cat's nasal passages if a sneeze cannot easily dislodge an object that might be trapped there. If you notice that something seems stuck in its nose, monitor their condition and promptly seek proper care from your trusted vet!

5. Dental Issues 

Sometimes, the cause of cats' sneezing does not come from their noses; it may also be because of some dental issues they are experiencing—especially if it involves root infections. When their tooth becomes infected, certain bacteria can spread to their sinuses, which can cause inflammation and trigger sneezing episodes.

Ensure your cat gets regular dental care to avoid further complications in its nasal features. Set regular dental check-ups for them, and you'll both thank yourself in the long run.

6. Allergic Reactions to Pollens

Besides their naturally sensitive noses, cats can also develop allergies to pollen. While it's less common, when they inhale these allergens, their bodies can react by releasing histamines as if they're under attack. These histamines can cause swelling and irritation in their noses, prompting sneezing to expel the allergens. To confirm allergies, check for watery eyes as an additional symptom.

7. Intranasal Vaccination Effects

Yes, a nasal vaccine is essential for cats to have to protect their respiratory systems, but this may also cause them to have a sneezing fit. Fret not, though; it's just a common side effect and will even bolster their immune system against respiratory illnesses in the long run.
