Cat Sneezing: What Does It Mean?


So your cat is sneezing – perhaps one of the cutest things found to occur in nature (besides kittens falling over, that is). While it’s adorable-and-a-half, a sneezing cat could in fact be the sign of a serious illness. We’ve put this brief guide together so that you can better understand the possible causes of your cat’s sneezing, what it means for their health and when it’s best to get the vet involved.

Don’t panic yet – there are plenty of simple, less worrying explanations, too. Let’s take a look at what it could be.  

Sometimes household cleaners, especially those with strong chemical scents will summon a prompt achew! While a sneeze or two is as normal as an appetite for mice, it’s not so clear-cut when your cat is sneezing over and over, repetitively for long periods of time.

First of all, if your cat is suddenly sneezing in bursts, ask yourself if there are any other symptoms, anything else out of the ordinary whether it’s their behaviour or physical appearance.


Symptoms to look for:

There are a list of possible infections that could be the cause of your cat’s sneezing spells. We’ll go into these in detail shortly but for now, here are some signs that all may not be well with your sneezing feline.

  • Heavy coughing or wheezing
  • Diarrhoea
  • Green or yellow discharge from the nose
  • A fever
  • Drooling from the mouth
  • Poor coat – dry or patchy with heavy malting
  • Weight loss
  • Difficulty breathing
  • Lack of enthusiasm for food

Whether or not you notice anything unusual, if your cat’s been sneezing for more than several days and they’re not prone to allergies, it’s time to see the vet just in case and for your peace of mind.


After taking a look at the symptoms your vet will do some tests.

While nothing can be determined without tests being performed, your vet will almost always suspect a virus is the cause of your cat’s sneezing. You may be asked questions about your cat’s health history or the state of the cat’s home environment, but only tests will answer this for certain.

Your vet will take swabs of the inside of your cat’s mouth, nose throat and eyes and send them away for testing.


What are the results likely to be?

Just like that cold or dose of flu we get when we can least afford it, the most likely cause of your cat’s sneezing is a mild viral or bacterial infection.

The most common viral infections that cause sneezing are feline herpes and feline calicivirus. While these viruses aren’t necessarily dangerous, if left untreated other more serious infections may develop. Feline herpes, for example, can often lead to a further bacterial infection but can be treated with a course of antibiotics.


What could it be – are there more serious possibilities?

Sneezing can be the first signs of a long list of other serious illnesses and conditions. Some of the more serious are feline leukaemia and feline immunodeficiency virus (FIV) or ‘cat AIDS’. Feline leukaemia is in most cases fatal and FIV attacks the cat’s immune system, leaving them vulnerable to further infection and serious, life-threatening illness.

Other infections that cause sneezing in cats include:

  • Bordetella
  • Feline Chlamydia
  • Mycoplasma
  • Feline infectious peritonitis

Of course there’s no need to jump to conclusions and it’s important to remember that only your vet will be able to make an informed assessment of your cat’s health. Get in touch with the vet if you’re concerned and organise an appointment as soon as possible.

If your cat doesn’t come into contact with other cats and spends its time indoors, it’s far more likely that your cat is having an allergic reaction. Often you can help your cat’s sneezes by simply tracking down anything new to the house that might be the culprit.

Remember, cigarette smoke, scented candles, new perfume, pollen, chemical cleaners, pest sprays, mould and excessive levels of dust are all common causes cat sneezing. Even certain kitty litter brands can cause an allergic reaction, especially if they’re of poor quality and dusty.
