Why Does My Kitten Keep Sneezing?

If your kitten has been sneezing a lot and you’re wondering why there are many reasons why this could be happening. Some of these reasons include allergies, virus or bacterial infections, parasites, foreign body in the nasal cavity, asthma, or sinus infection. In this article, we will explore some of these potential causes and how to fix them!


Allergies can be caused by pollen, dander, and dust. The symptoms of allergies can include a runny nose, watery eyes, coughing, and sneezing. If your kitten is exhibiting any of these symptoms then they are likely allergic to something in the environment.

In this case, you should take them outside for a little while or give them some allergy medication like Benadryl which will help with their itchy red eyes and soothe their throat from all that icky mucus build-up!

Allergies in kittens can be triggered by a number of things. It could be something they ate and their body didn’t respond well to it or it could be seasonal allergies.

Respiratory Infection

Respiratory infection in cats looks like sneezing, but may also include a fever and eye drainage. Respiratory infections in cats are typically caused by bacteria or viruses and the best treatment for it is going to be rest and antibiotics!

If you’ve ruled out allergies then your kitten likely has an infection that requires a visit to the vet’s office – don’t wait too long because respiratory infections can get worse! An untreated respiratory infection can lead to pneumonia, which is why it’s important to have your kitten checked out asap.

Feline Asthma 

Cats with feline asthma are at risk for developing bronchitis, pneumonia, and even heart problems in severe cases.

It’s important to keep your kitten inside during allergy season so they’re not exposed to allergens like pollen and changing the cat litter box often is also a good idea! There are many ways we can help our furry friends when it comes to respiratory allergies because as you know prevention is always better than cure.

Why Does My Kitten Keep Sneezing?

When do you know your kitten might have asthma?

Look for the most common signs of asthma:

  • Sneezing
  • Labored breathing
  • Wheezing or whistling sounds when inhaling and exhaling (this is why it’s important to have your kitten checked out asap)

If you notice any of the signs, please take them to a veterinarian for an exam. Many veterinarians will even do blood work at no charge during this time which can help identify what might be causing their symptoms.

If they need medication, most vets are happy to prescribe some if needed! You’ll also want to keep track of how often the sneezings happen because oftentimes asthma happens in periods and not all day every day–which is why prevention methods are so helpful! A checkup can also help discover if your cat has any heart murmur.

What to do if my kitten has asthma

If you just found out your kitten has asthma, you can still help them live a normal life. Through medications, you can make it so they only have asthma symptoms at certain times–like when there’s pollen in the air or if their allergies are out of control. Not all cats need to take medication for this condition but many do!

If your kitten has been diagnosed with asthma, be sure to read up on what might be triggering his/her flare-ups and address those as soon as possible to keep them from happening again. Consider using an antihistamine if things like dust mites trigger allergic reactions and talk about potential triggers like stress during vet visits too!

Can a kitten grow out of ashtma?

Some kittens grow out of asthma, while others don’t. It’s really hard to tell why some get asthma and then end up growing out of it, but one theory is that their immune systems are more sensitive when they’re younger so the trigger for causing an episode might be different than someone who had a previous history with asthma before getting it as a kitten.

This means you’ll want to keep track every day–or at least once or twice per week–of how often your kitty sneezes because if they got better in between periods (and not all the time) without any changes then chances are high that they will have grown out of their symptoms!

Congestion From a Cold or Flu Virus 

Like any cold or flu, congestion can lead to sneezing and a runny nose. The best way to help your kitten feel better is by keeping them warm, give them lots of fluids and make sure they’re well fed!


If a cat’s sneezing was accompanied by a fever, rapid breathing, or difficulty breathing then they could have pneumonia. Cats with this condition need to stay in bed and receive fluids intravenously so that their body can recover!

If your kitten is sneezing without any other symptoms like coughing, wheezing or lethargy then it’s likely just allergies but if you’re unsure please take them to the vet for an exam as soon as possible because we don’t want anything worse than allergies on your hands.

Pneumonia in cats can be fatal if not treated promptly, so it’s important to keep an eye out for symptoms.

Other Things to Look Out For When Your Kitten is Sneezing a Lot

There is a long list of reasons why a kitten could be sneezing so we’re going to go through a few of the most common ones. Dust and dander can irritate your kitten’s nose causing them to sneeze, so try to keep their environment as clean as possible with plenty of fresh air. If there is an animal in the house that has been ill then it could be contagious.

Sneezing blood

Is your kitten sneezing blood? Does it have a runny nose or nasal discharge that is clear greenish-yellow, or rusty brown? This could be a sign of a respiratory tract infection.

Coughing up blood or brownish phlegm (sputum) that may have an onion smell. This could be due to something like lung cancer, pneumonia, bronchitis, or even heart disease and is usually seen in older cats of any age but can happen at any time.

It’s always better to err on the side of caution so if you notice your kitten sneezing without other symptoms then please take them for a visit with their vet as soon as possible just so they can get a check-up done and rule out anything worse than allergies!

Odor around the mouth and eyes

If you notice an unpleasant odor coming from their nostrils then they may have infectious rhinitis which sometimes accompanies viral infections in cats. This usually results in fever and eye inflammation as well.

Eyes are watering more than normal

Cats typically don’t produce tears like humans so anything outside of the norm needs to be looked into by a vet! If there’s excessive tearing on one side of the face it could mean that their ducts are inflamed because of either allergies, infection (viral), or environmental irritants such as smoke or

Sneezing and wheezing

Excessive sneezing and wheezing can be a sign of congested sinuses or respiratory infection, so if they’re also sniffling and showing signs of discharge from their nose then you should take them to the vet!

After a bath

After giving your kitten a bath, you should allow them to dry off before they sleep and then put a towel down so they can rest on it. It’s also important that you don’t use any fabric softener because this will irritate their skin, which could cause sneezing!

If your kitten has been exposed to other cats who are sick or if there is an allergen in your home (such as dust mites), these factors may be why he/she is constantly sneezing.
