A cat sneezing might not always be a cause of concern - until you hear them go "Achoo!" a few hundred times. Ranging from serious illnesses to more minor causes, here's why your cat is sneezing - and what you can do to prevent it.
Ever heard a distinctly…feline-sounding “Achoo!” and looked over and found your cat was the culprit? Wondering: why is my cat sneezing? (And why is it kind of cute when it does?)
Well, as it turns out, sneezing is the body’s way of clearing irritants like smoke, dust, and pollen from the nasal passages. (And when your kitty sneezes…well, you have to admit it’s kind of cute.)
Now a few cat sneezes here and there are no big deal, but excessive sneezing in cats can signal something’s wrong. So we’re going to cover the potential reasons for a cat sneezing, how you can help your kitty avoid illness, and how monitoring your cat’s health with a dedicated pet tracker is a solution.
Just as in humans, cat sneezing may occur when their noses becomes irritated by particles in the air – or by a virus. During a sneeze, air is forced out of the nose, whisking away the annoying irritant.
But watch your cat closely – their sneeze may not be a sneeze! Your cat may be:
Coughing
Gagging
Reverse sneezing
Hiccupping
Or even retching
💡 So before you seek treatment for your cat’s sneezing issues, make sure they’re actually sneezing. Take a video of the sneezing episode to show your vet to help them understand the problem.
It’s helpful to keep an eye out if there’s a pattern to your cat sneezing.
Does it happen at the same time every day?
Does your kitty always sneeze upon entering a certain room in your house?
Determining if there’s a pattern to your cat’s sneezing can help narrow down the cause.
Why is my cat sneezing? The main causes & culprits
Once you know when, where, and how often your cat’s sneezes are happening, it’s time to figure out why your kitty is sneezing. Here are some of the common reasons that cats sneeze.
Upper respiratory infections
Upper respiratory infections, which are caused by viruses, are the most likely reason that your cat is sneezing. These viral infections are a lot like the common cold that we humans experience, and they can range from mild to severe.
Feline Herpesvirus 1 (FHV – 1)
The most common virus to cause upper respiratory infections in cats is Feline Herpesvirus 1 (FHV-1). Cats infected with FHV-1 experience sneezing, nasal discharge, coughing, and conjunctivitis.
FHV-1 is passed from cat to cat through oral, nasal, or eye secretions.
An FHV-1 infection usually runs its course in four to seven days.
Like all herpes viruses, FHV-1 is rarely cleared from the cat’s body. Instead, it lies dormant and flares up from time to time. Seasonal changes, stress and other factors can spur a flare-up.
Ask your veterinarian about treatments to decrease viral reproduction and ease your kitty’s symptoms.
Feline Immunodeficiency Virus (FIV)
Feline Immunodeficiency Virus (FIV) is another virus that can cause your cat to sneeze.
FIV attacks and weakens your cat’s immune defenses, so it becomes easier for affected cats to develop respiratory infections.
Similar to HIV in humans (Human Immunodeficiency Virus), FIV is not common. Only a small percentage of cats show exposure to the virus.
💡 Humans cannot be infected by FIV. This virus is usually transmitted from cat to cat through bites that break the skin and allow bodily fluids to mingle.
Feline Calicivirus
Feline Calicivirus is another organism that can cause sneezing in cats.
This virus is highly contagious and causes upper respiratory infections in cats. It can also cause other seemingly unrelated ailments, including chronic gingivitis (gum inflammation) and limping due to joint inflammation.
💡Don’t neglect your cat’s dental care routine – make sure to check in with your vet for regular dental cleanings for kitty, so you can catch on to any health issues early.
Nasal and sinus issues
Inflammation of the tissues lining the nose and sinuses can cause a “stuffy nose” in your kitty. These conditions, called rhinitis and sinusitis, are common complications of an upper respiratory infection.
When your cat sneezes very often every single day for weeks, they may be experiencing a chronic upper respiratory condition.
This often means that their nasal passages and immune system have been damaged or weakened from previous infections.
⚠️ This type of condition will not resolve on its own. So get advice from your veterinarian on supportive treatments that will make your kitty more comfortable.
Allergens
Your cat’s nasal passages might be irritated by:
Particles in the air
Scented household items like perfume or scented candles
Mold
Pollen
Dust (including from their litter box)
Common household items, like cleaning chemicals
Smoke
All these may cause your cat to sneeze as an allergic reaction.
Sometimes, a larger object, like a piece of grass or small clump of dirt may lodge in your kitty’s nose. By sneezing, your cat’s body is trying to expel the object naturally.
⚠️ If sneezing doesn’t do the trick and you are certain that an object is lodged in your cat’s nose, head to your vet ASAP. Foreign material lodged in the nose can cause a breathing blockage.
Inflammation or infection of a tooth
You might be unaware that dental problems can cause your cat to sneeze, but it’s true!
The roots of the teeth in a cat’s upper jaw are right beside the nasal passages.
So any infection of the teeth can affect the nasal passages.
When a cat’s tooth root is infected or inflamed, it can create drainage into the sinuses and cause sneezing.
Gingivitis, abscesses, ulcers, rotting teeth, and other dental diseases can all cause sneezing. (Especially when an infection becomes established in the sinuses.) Your veterinarian can diagnose this condition and solve your kitty’s sneezing problem.
Bacterial infections
Bacterial infections can also cause upper respiratory infections in cats. (Like, for example, bacteria like mycoplasma.)
But sometimes, your cat might get infected as a result of a virus – which then leads to bacteria forming. How does this work?
Let’s say a virus gives your cat an upper respiratory infection.
Some fluid created during the upper respiratory infection could get trapped in the sinuses
Bacteria and viruses can grow in that fluid, causing inflammation or infection.
💡 Unlike viral infections, bacterial infections can be treated with antibiotics. Make an appointment with your veterinarian if you suspect your cat has a bacterial infection.
Fungal infections
A fungus called cryptococcus can grow in your cat’s nasal passages and cause your cat to sneeze.
To determine if there is a fungal infection in your kitty’s nose, your veterinarian will need to collect a sample and have it analyzed. Luckily there are several treatment options for fungal infections in cats.
Nasal neoplasia (nasal tumors)
Nasal tumors are an unlikely but possible cause of your cat’s persistent sneezing. Older cats are more at risk for nasal tumors, which make up less than 1% of all tumors in cats.
Nasal tumors will typically cause nasal discharge and possibly sneezing, among other symptoms. If your cat exhibits noisy breathing along with sneezing and drainage from the nose, get it checked as soon as possible.
Feline leukemia
A virus that infects only cats, feline leukemia can present itself with a wide array of symptoms, including those that mimic an upper respiratory infection.
A cat with feline leukemia may cough, sneeze, or have discharge from the eyes and nose.
Cats may also become lethargic, lose weight, and experience aloss of appetite.
Your veterinarian will need to perform a blood test to determine if your cat has feline leukemia.
💡Fortunately, there is a vaccine available to prevent your cat from becoming infected. Ask your veterinarian if they recommend this vaccine based on your cat’s lifestyle.
How to stop a cat from catching a cold
As the saying goes, an ounce of prevention is worth a pound of cure. For your cat, this means keeping your furry friend healthy on a daily basis to keep them from catching a cold.
Keeping your kitty on schedule with annual and seasonal vaccinations is the most important way to protect them from vaccine-preventable illnesses.
Maintain a solid foundation for your cat’s health by providing nutritious food, fresh water, daily play sessions, belly rubs, and plenty of opportunities to chill out on your lap. After all, you are your cat’s favorite human (even if they sometimes act like they don’t care)!
But most importantly…
Figure out where exactly your cat is catching a virus from
Cats are also naturally curious and love to explore. (Yes, even your indoor cat.) It’s an evolutionary habit wired into their DNA.
⚠️ But with their love for wandering and exploring, your cat is always at risk of running into something potentially allergic or infectious.
So imagine getting a picture of your cat’s most frequent haunts – and which spots they like to wander off to best?
Or getting an immediate escape alert on your phone when your cat wanders off beyond a “safe zone” that you’ve defined – so you can intervene?
Or being able to track your cat’s real-time location before they wander off into your neighbor’s pollen-riddled garden?
It’s why Tractive pet parents around the world – just like you – are investing in our life-saving technology. With just a glance at your phone, you can now figure out exactly where your cat’s off wandering.(Or hiding, hunting, or just hanging out.)
So you can better prevent them from heading somewhere they could potentially pick up something infectious – or even more dangerous.
Know everywhere your cat goes
See where they are in real-time, no matter how far they go. Get alerts if they roam too far home. Find out where they’ve been and discover their favorite spots. Let others track with you.
“Tractive is my #1 recommendation when it comes to cat trackers. It’s specifically designed for tracking cats so you are sure that it is safe for your cats to use.”

How do you treat a sneezing cat?
Before you can treat a sneezing cat, you need to know what’s causing the sneezing.
First, take some time to observe your cat closely and note how frequently they sneeze, if there’s nasal discharge, or eye discharge.
If sneezing episodes sound unusual, take a video so your vet can see and hear your cat sneezing.
Pay attention to your cat’s sleep. If they breathe more rapidly when asleep or relaxing, they may be coming down with a virus.
Then make an appointment with your veterinarian to review what you’ve observed and explain all of your cat’s symptoms.
Your vet may take some samples and run a few tests to try and determine the cause of your cat’s sneezing. There are a few non-medication options for treating the symptoms of stuffy nose and upper respiratory infections in cats.
Nasal lavage
In nasal lavage, the cat is placed under anesthesia and a sterile fluid is used to flush out the nasal passages. This procedure can help dislodge a foreign body, or provide relief from congestion.
Humidifier
A humidifier may help your cat find relief from sneezing and congestion, especially in cold dry weather.
Place a small room humidifier, available at most drug stores and big box stores, near the places where your cat sleeps
Turn it on at night.
The humidity created by this device can help to thin the mucus in the nasal passages, allowing it to drain away more readily.
Accupressure
Accupressure can be applied in precise locations on your cat’s face to help encourage drainage form the nasal passages and sinuses.
Is it normal for my cat to sneeze multiple times in a row?
An occasional sneeze is most likely nothing to worry about. But what if your kitty has a sneezing fit and sneezes three, four, or more times in a row? That’s normal too.
Just keep an eye on your furball to see if the sneezing increases or persists for several days.
Cat sneezing too much? What to do
If you worry that your cat is sneezing too much, take a closer look.
Does your kitty show other symptoms, like eye discharge or a runny nose?
Are they eating less, or are they lethargic?
💡 It’s all of these symptoms together that may signal a problem to the veterinarian. Else, a few sneezes a day are nothing to worryabout in the absence of other symptoms.
When is it time to see a vet?
If your kitty sneezes only once in a while, and has no other symptoms of illness, a visit to the vet is probably not needed (except for regular checkups and to get annual vaccinations, of course).
If frequent sneezing happens and your cat has other symptoms like discharge from the eyes and nose, a visit to the veterinarian may be warranted.
After all, some of the causes of sneezing in cats can be serious. If your cat exhibits one or more of the symptoms below in addition to sneezing, give the vet’s office a call.
Nasal discharge
Abnormal breathing or difficulty breathing
Eye discharge
Fever
Loss of appetite
Pawing at the face
Breathing rapidly during sleep
Your vet will be able to recommend the right treatment for your cat’s sneezing, based on the cause. So don’t hesitate to bring your kitty in for an appointment – your cat depends on you for their health and safety.
You and your cat’s care team can work together to keep your kitty healthy and sneeze-free.
How to catch on to your cat’s health issues early
One of the first signs your cat may be developing a sickness or coming down with an infection? If they seem more lethargic – or less active – than before.
Because after all, not all serious health conditions develop overnight. Rather, they develop gradually over many days – and usually begin with sneaky, easy-to-miss symptoms like lethargy or sleep disturbances.
💡 For a cat sneezing all the time – one of the first signs they’re coming down with an infection is if their breathing sounds more labored, even when they’re asleep or just chilling.
Which is why it makes sense to track your cat’s activity and sleep – to catch on a change in their behaviors early on.
And if you’ve invested in a Tractive device – like smart pet parents around the world – you’re now that much closer to taking an active role in your cat’s health and wellbeing.
Whether your cat’s sleeping patterns have changed – i.e., whether they’re sleeping more or less
All of which can help you pick up on a health emergency early on. (And avoid a massive vet bill down the line.)
“Everything we build puts pets and pet parents first. It’s why we’ve built one device that tracks all aspects of your pet’s safety, from location to wellness. So you can holistically keep them both safe and happy.”
– Sebastian Raab, Product Manager at Tractive & occasional pet sitter
Track your cat’s sleep – so you can catch on early to a sleep disturbance. (Like labored breathing – which can indicate the start of a viral infection.)
Keep an eye out for symptoms like lethargy – which can indicate your cat is struggling with an infection or sickness. With your cat’s Activity Tracking data at hand, you’re also likely to have a more productive conversation with your vet.
With these steps, you’re that much closer to a longer, happier, healthier and sneeze-free life with your feline friend.
