25 Causes Why is My Cat Sneezing, Symptoms and Treatment

cat sneezing

While we may think of sneezing as a sign of being sick, it is a reflex that occurs when your body reacts to an irritant or foreign particle in the nose. Why is my cat sneezing? And what are the symptoms of it? Cats can have the same symptoms of sneezing and nasal discharge as humans. Cat sneezing can be caused by anything from viral infections to allergies and irritants such as dust mites or pollen.

Why is my Cat Sneezing After Falling?

You describe head trauma. Concussion symptoms sound likely after being hit hard enough in the head and face. Face or nasal sinus fractures are possible. The swelling on his nose indicates trauma to his nose. Perhaps something is broken or inflamed. Generally, sneezing is caused by nasal inflammation, pain, or irritation. The bleeding should stop; if he acts abnormal, is sleepy, and does not eat or play, he needs a vet. Swelling and sneezing can be observed. The swelling should improve if it doesn’t by Monday.

Why am I sneezing around my cat? OR Why am I suddenly allergic to my cat?

After petting or playing with a cat, you might have a cat allergy if your nose runs, your eyes water, or you start sneezing and wheezing. Cat allergies can contribute to constant allergy symptoms at work, school, daycare, or any indoor environment, even if there’s no cat around.

Many cats produce allergens (proteins that cause allergies). Skin, fur, and saliva contain these allergens. There is no evidence that cats are hypoallergenic (meaning they do not cause allergies). There are more cat allergens in homes with more cats. Cat allergen levels are not associated with a cat’s hair length, sex, or time spent indoors.

Cats’ coats can also contain allergens. Dust or pollen, not the cat, Cato dust allergy.

Most Common Problem: Why is My Cat Sneezing So Much

Your cat may sneeze for a variety of reasons. Sneezing is the body’s reflex to clear foreign matter entering the nasal cavity. It’s also involuntary, so you can’t tell your cat to stop sneezing. She’ll keep doing it until her nose is clear.

If your kitty has been sneezing for more than two days, other underlying issues (like viral infections) could be at play. If you’re concerned about your pet’s health, take her to the vet as soon as possible.

Cat Sneezing is an Involuntary Reflex

 Why is my cat sneezing? Sneezing is an involuntary reflex. You can’t control it; as such, sneezing isn’t a sign of anything in particular. It doesn’t mean your cat has a cold or any other disease; it’s simply another bodily reaction to something irritating the nose.

Unlike coughing, which is also a reflex but occurs more frequently with certain diseases like kennel cough or bronchitis (inflammation of the airways), sneezing alone does not indicate any illness at all. Rather than being indicative of an infection or allergy, sneezing may arise from irritation caused by dust mites or pollen in the air.

Why is my Elderly Cat Sneezing?

If you have an elderly cat, you may notice your kitty sneezing more than usual. An older animal’s immune system isn’t as strong, and they are at greater risk of developing respiratory infections such as the feline calicivirus (FCV), which can cause sneezing. “I recommend reading this article if you do not know Can Cats Eat Different Healthy Fruits and Veggies.”

If you own an elderly cat, it’s essential to keep them inside so they don’t come into contact with other cats carrying FCV or other diseases that could affect your pet. If you must let them out, keep your senior cat indoors without direct supervision.

In addition to preventing exposure to potential illnesses, keeping your senior pet indoors reduces their chances of being hit by a car or attacked by a dog or wildlife.

Any Foreign Material that Irritates the Nasal Passages may Cause Sneezing

Your cat sneezing due to exposure to something in the environment, including:

  • Dust
  • Pollens
  • Mould spores
  • Mites and other insects that live in carpets and upholstery (for example, cockroaches) can also be inhaled by cats and irritate their nasal passages. Even if you don’t see an insect crawling on your cat’s face or body, consider it possible for him to have inhaled one.

The most common cause of feline allergies is food intolerance; however, it’s also possible for your pet to develop allergies from dander from dogs or other animals or even from dust mites in his bedding and bed. If you’re noticing changes in your cat’s behaviour but he doesn’t seem physically ill (such as vomiting), suspect allergies first before considering any other reason why he might be sneezing excessively. 

Cats with respiratory infections will also have trouble breathing through their noses when they have congestion and thick secretions making their sinuses more prone to infection; therefore, it’s essential to clean out these areas regularly due to the increased risk of bacterial growth within them.”

Sneezing May be a Sign of Infection

Sneezing is an uncontrollable reflex that several factors can trigger. Why is my cat sneezing because of a bacterial or viral infection, an allergic reaction to something in the environment, or an environmental irritant such as dust mites? Sneezing may signify a cold (rhinotracheitis), flu (influenza), or asthma. It can also occur when your cat has an upper respiratory tract infection (URTI).

 If you notice that your cat has been sneezing for more than a day and his eyes are watering, take him to see your veterinarian immediately because this could signal an eye problem called conjunctivitis requiring immediate treatment.

In rare cases, sneezing is associated with nasal tumors or sinus infections which require surgery if they are severe enough to affect the quality of life of your pet.

Another reason cats sneeze is that they have a cold or the flu. If your cat has been sick for more than a week and he’s still sneezing, it’s time to check him out by a vet. Sneezing may be caused by an upper respiratory tract infection (URTI) or asthma. Your vet will diagnose these issues and prescribe antibiotics if necessary.

Infectious Agents can Enter the Body in Many Ways

Infectious agents can enter the body in many ways. The most common route of infection is via inhalation of an infectious agent into nasal passages, where it causes inflammation and mucus secretion. In cats, viral infections are usually mild and self-limiting but may cause severe disease if there is an underlying heart or lung condition.

The most common viruses that infect cats are Feline Herpesvirus Type 1 (FHV-1), feline calicivirus (FCV) and feline parvovirus (FPV). These viruses are highly contagious to other cats: they spread quickly among groups of kittens or cats living together at shelters or catteries and through social contact between animals outside these environments.

Sneezing can Indicate Respiratory Allergies(or Sinus and Nasal Allergies)

Sneezing can indicate several different health problems. If your cat frequently sneezes, you must visit your veterinarian as soon as possible to rule out any severe conditions. A complete physical examination and blood work will help determine the underlying cause of the sneezing. Common causes include:

  • Respiratory allergies(or sinus and nasal allergies). Your cat may be allergic to something in the house, such as pollen or dust mites, or outside, like grasses and trees. These allergens are inhaled through airways into your pet’s lungs, where immune cells react by releasing histamines that cause inflammation and irritation within them—which leads to sneezing.

Many Viruses are Associated with Sneezing and Nasal Discharge in Cats

Some of these infections are mild and others can be fatal, so it is essential to find out what’s causing your cat’s sneezing so that you can treat it.

  • Cat flu or feline infectious peritonitis (FIP) is a viral disease caused by coronaviruses. It’s characterized by fever, lethargy and coughing up blood. The virus can spread from one cat to another via bodily fluids including saliva, tears, urine and faeces. If there is an active coronavirus infection in your household, everyone should be vaccinated against FIP as soon as possible because once an animal has contracted the virus, there is no cure.
  • Cat colds or rhinotracheitis occur when your feline catches a cold from another cat either through direct contacts such as grooming each other or indirect contact like sharing the same litter tray or eating utensils.
  • Calicivirus is a highly contagious respiratory infection which causes symptoms similar to those found in the common cold, such as sneezing and runny nose, but also eye problems which may result in blindness if left untreated.* Panleukopenia (also known as feline distemper) occurs when an infected cat coughs up white foam while running high temperature with severe diarrhoea, which leads to dehydration rapidly requiring hospitalization.
  • Herpesvirus causes conjunctivitis (inflammation of membranes surrounding eyes) leading to corneal ulcers that may cause blindness if not treated properly within 48 hours after onset.* Feline leukaemia virus causes lymphoma (cancer involving immune cells called lymphocytes), leukaemia (cancer arising from bone marrow stem cells), skin cancer etcetera.

The cat Keeps Sneezing But Seems Fine

If your cat is sneezing but seems to be otherwise healthy, the most likely causes are an allergy or a viral infection. These conditions can cause sneezing (and other symptoms) without complications, such as fever, discharge from the nose or mouth, and even coughing. 

Your veterinarian can diagnose these conditions with a physical examination and blood work if necessary. In some cases, treatment may involve antihistamines or antibiotics; however, it’s important not to give aspirin or ibuprofen to your cat because both medications can be harmful to them—even fatal in high doses.

Why Does My Cat Keep Sneezing?

If your cat has been sneezing for a few days and is otherwise acting normal, the cause of the sneezing is likely unrelated to any other problems. If, on the other hand, your cat seems lethargic or refuses to eat or drink water, then you might have cause for concern.

 Cats are masters at hiding pain and sickness, so it can be challenging to know exactly what’s happening inside their bodies; however, when cats show clear signs of illness (such as sneezing), we should take them seriously.

As mentioned above, one of the most common causes of sneezing in cats is an upper respiratory infection (URTI). This type of illness affects more than just cats: dogs also suffer from URTIs every day due to their close contact with humans who carry germs around with them everywhere they go.

Why is My Indoor Cat Sneezing

  • If your cat is sneezing and not eating, this could be the result of a fever.
  • If your cat has watery eyes, it might have an upper respiratory infection (URI).
  • Using a digital thermometer is the best way to tell if your cat has a fever. The average normal temperature for cats is 100 degrees Fahrenheit; however, if you are concerned that your pet may have developed an illness, it’s always best to get them checked out by a veterinarian.
  • There are several causes of sneezes in cats, including allergies and feline distemper virus (also known as panleukopenia), but one of the most common reasons why pets will start sneezing is because they have something stuck inside their nose that irritates them when they breathe or try to eat or drink.
  •  It often happens with indoor-only cats who spend their days sleeping on soft surfaces like blankets instead of hardwood floors where there aren’t any hairs sticking up into their nostrils all day long.”

Why is my Cat Sneezing and Not Eating?

You must consult your vet for a proper diagnosis if you notice your cat sneezing and not eating. If the cause of their sneezing is due to allergies or an upper respiratory infection, they will need medication to feel better. You should read this article If you did not know How Dried Cat Food Per Day Serving at Home in 2022.

 To help with this process, you can regularly give them water so they don’t get dehydrated while recovering. It would help if you also tried to keep them away from other animals exhibiting the same symptoms because there could be an airborne disease that could spread quickly in a small home environment such as yours.

Why is my Cat Sneezing and Coughing?

A cat who’s sneezing and coughing may be in respiratory distress. If your cat is sneezing, it’s essential to thoroughly examine the mucus to determine if they are having an upper respiratory tract infection (URI). A URI can cause sneezing and coughing, watery eyes and nose discharge, not eating or drinking, fever, lethargy and loss of appetite.

If you’ve ruled out other potential causes for the cat’s sneezing by checking for allergies or other illnesses that might require treatment, such as antibiotics, you should consider whether there’s a more severe issue at hand, such as asthma or a heart condition. The key here is that if symptoms are constant over several days, they should not be ignored; instead, seek veterinary attention immediately as these symptoms could indicate something much more serious going on with your pet.

Why is my Cat Sneezing and having Watery Eyes?

If your cat sneezes and has watery eyes, it will likely experience an upper respiratory infection. A virus or bacteria can cause this, but the most common cause is the feline herpes virus (FHV-1).

If your cat is sneezing and not eating, this may be due to allergies or other health issues that require veterinary attention. Have them checked out as soon as possible so you can get them on the road to recovery.

How to Tell if Your Cat has a Fever

You should be able to tell if your cat has a fever by looking at its gums. If they are pale and the cat is lethargic, it may have a fever. Cats with high temperatures will also often feel hot to the touch, so take note of that.

If you suspect your pet’s temperature is above average, take them to the vet immediately. A vet can administer different medicines depending on what type of illness they think it might be. However, if they aren’t sure themselves, then they might recommend some paracetamol or ibuprofen for pain relief until they get back with more information on what could be causing this problem in the first place.

What Causes Sneezes when my cat is sneezing

  • Sneezing and coughing are common in cats, as they are in humans. It can be due to allergies or infections.
  • Watery eyes, sneezing, and not eating are signs of the cat being sick with an upper respiratory infection. A condition that causes mild fever, runny nose, and watery eyes.
  • If your cat has a fever over 101 degrees Fahrenheit (38 degrees Celsius), take it to a veterinarian immediately to ensure it doesn’t have an infection that needs treatment too quickly for you to get help on your own.

Cat Upper Respiratory Infection

If your cat is sneezing and coughing, she may have an upper respiratory infection.

In the early stages of a feline upper respiratory infection, you’ll likely notice your cat sneezing, coughing, and having runny eyes or nose. If these symptoms persist for more than 24 hours, it could be because the infection has been going on for some time already. In this case:

  • Your cat will also likely experience watery eyes and a watery nasal discharge that drips into her mouth frequently.
  • You may see lethargy and other signs of illness such as sneezing or fever. If your cat is lethargic or seems to be sleeping more than usual (cats typically sleep between 14-18 hours each day), this can indicate something like an elevated heart rate from stress due to pain caused by inflammation that results from an upper respiratory illness; this requires immediate veterinary attention because it can lead quickly towards kidney failure if left untreated.

Cat Stuffy Nose

  • Your kitty may have a stuffy nose, especially if you notice them sneezing or coughing. Stuffy noses can be caused by allergies, infections and viruses that make the mucus membranes of your cat’s nose inflamed and swollen. You can help soothe your kitty with a humidifier that will add moisture to the air, which helps loosen secretions in their lungs and throat.
  • A cat sneezing is one of the most common reasons for a cat’s congestion (and just as annoying to us). If your cat has repeatedly been sneezing for more than 24 hours and has watery eyes, as well as sneezing and not eating or drinking much more than usual — you should contact your vet immediately! These signs of an upper respiratory infection (URI) need immediate treatment.

Why is my Cat Sneezing: Treatment

There are many possible causes of sneezing in cats, including dust, pollen and even temperature changes. No matter the underlying cause, the most effective treatment is to get your cat to a veterinarian as soon as possible. Once you’ve seen your vet, they’ll be able to recommend a course of treatment based on their knowledge of your cat’s symptoms and medical history.

The most common treatment for sneezing in cats is antibiotics. In some cases, this can clear up an infection so that there’s no need for further care or medication; however, it’s important not to stop taking antibiotics prematurely because doing so will likely result in relapse later on.

My Cat Sneezes a Lot, but no Discharge

  • If your cat is sneezing a lot and not having any discharge, they likely have an upper respiratory infection.
  • Some of the other symptoms you may notice if your cat is suffering from an upper respiratory infection include coughing, watery eyes and lethargy.

Home Remedies for Cats in Heat

If your cat is in heat, here are some things you can do to help:

  • Make sure that she has plenty of fresh water.
  • Put her food bowl in an area where she’ll be able to eat without being bothered by other cats or people.
  • Put up a gate or door so that she doesn’t have as much access to the rest of the house during this sensitive time. It will help keep her from becoming overwhelmed by other pets and people who may not understand what’s going on with her body and might try to take advantage of it (which could stress out your cat even more).

Upper Respiratory Infection in Kittens

It is common for kittens to have upper respiratory infections and viruses that affect the sinuses and airways. The viruses can be passed between cats as well as people. If you suspect your kitten has an upper respiratory infection, see your vet right away.

The signs of upper respiratory infection include:

  • Sneezing
  • Nasal congestion (nose is full)
  • Runny eyes (may be watery)
  • Discharge from eyes or nose

Why is My Snot Orange in kitten

There are several reasons why your cat’s snot might be orange. Orange snot is a sign of a bacterial infection, fungal infection, viral infection, or parasitic infection.

When your cat has an upper respiratory tract infection (URTI), its nasal passages become congested due to the body’s immune response to an invading organism. It can lead to excess mucus production and drooling.

If your kitty’s discharge is colored orange or yellowish-orange instead of clear, this indicates that he has an upper respiratory tract infection (URTI). If the discharge turns greenish-yellow or brownish-yellow in colour, it may be time to schedule an appointment with your veterinarian because these colors are associated with more severe infections like feline herpesvirus type 1 (FHV1) or feline calicivirus (FCV).

My kitten is Sneezing and has Watery Eyes

There are several reasons why your cat might be sneezing. These include allergies, infections, cancer and other illnesses like a cold. Sneezing is also a symptom of asthma, sinus infections and nasal polyps. Some cats are allergic to certain environmental substances such as dust or pollen.

 The most common causes of sneezing in cats are:

  • Food allergies.
  • Bacterial or viral infections (like feline herpesvirus).
  • Cancerous tumours affect the nose or respiratory tract.
  • An upper respiratory infection such as feline viral rhinotracheitis (VFR) or calicivirus infection.

Kitten Sounds Congested But has no Discharge

Knowing the difference between a cat sneezing because of allergies and one with an infection is essential. If your pet is sneezing but has no discharge, this may indicate that he is suffering from allergies.

 The most common causes of sneezing in cats are:

  • Mould spores
  • Fungus spores (from outdoor grasses and trees)
  • Dust mites or other arthropods (carpet beetles, etc.)
  • Pollens (from flowers, trees, weeds and grasses)


Your cat may have an upper respiratory infection or URI. It is an infection of the mouth, nose and throat caused by bacteria or viruses. If your vet diagnoses this condition, they will probably prescribe anti-inflammatory medications such as antibiotics that fight infections to help ease the symptoms.
