A cat’s sneeze might seem adorable or amusing at first, but if it happens often or comes with other symptoms, it could be a sign of a deeper health concern. Like humans, cats sneeze to clear their nasal passages. However, if it happens frequently or persists for more than a few days, it's crucial to identify the cause and determine when to consult the vet.
In this blog, we’ll explore the most common reasons why cats sneeze, what signs to look out for, and how to keep your feline friend healthy and comfortable.
What Causes Cats to Sneeze?
1. Irritants in the Environment
Just like us, cats can sneeze when something tickles their nose. Common environmental irritants include:
- Dust
- Strong perfumes or air fresheners
- Cigarette smoke
- Cleaning products
- Pollen
If the sneezing happens occasionally and you’ve recently cleaned or used a new product at home, the cause may be as simple as a temporary irritant.
2. Allergies
Although allergies are more likely to cause skin or digestive symptoms in cats, sneezing can occasionally result from:
- Mold
- Pollen
- Certain foods
- Litter dust
Switching to a low-dust litter and removing potential allergens from your home may reduce sneezing episodes.
3. Upper Respiratory Infections (URIs)
One of the most common causes of chronic sneezing in cats is a viral or bacterial infection. These infections are prevalent in kittens and shelter cats.
Common pathogens include:
- Feline Herpesvirus (FHV-1)
- Calicivirus
- Chlamydia
- Bordetella
These infections often cause other symptoms like:
- Runny nose
- Watery or goopy eyes
- Loss of appetite
- Lethargy
- Fever
If your cat displays several symptoms, it's important to schedule a veterinary visit to ensure proper diagnosis and care.
Many cat parents are surprised to learn that problems with their cat’s teeth can cause sneezing. That’s because the roots of the upper teeth are located near the sinuses. Infections or abscesses in these teeth can irritate the sinuses and trigger sneezing.
Look out for:
- Bad breath
- Drooling
- Difficulty eating
- Pawing at the mouth
Routine dental exams play a key role in identifying and preventing these problems early on.
5. Foreign Objects
Sometimes, a blade of grass, a dust particle, or another tiny object can get lodged in your cat’s nasal passages, causing them to sneeze repeatedly. If the sneezing is sudden and intense, especially after coming indoors or playing outside, this might be the cause.
6. Nasal Polyps or Tumors
In older cats, persistent sneezing may be a sign of nasal polyps or tumors. These growths can block airflow and irritate the nasal passages, leading to:
- Chronic sneezing
- Nosebleeds
- Labored breathing
Early veterinary evaluation is key to diagnosing and managing such conditions.
When Should You See a Vet?
Sneezing once in a while isn’t usually a cause for concern. However, you should take your cat to the vet if they show any of the following symptoms:
- Sneezing continues for several days
- Mucus discharge from the nose (especially if yellow or green)
- Blood in the nose
- Loss of appetite
- Lethargy
- Eye discharge or swelling
- Breathing difficulties
- Drooling or signs of dental pain
Your veterinarian may perform a physical exam, X-rays, blood tests, or even a nasal scope to find out what’s causing the problem.
How to Help a Sneezing Cat at Home
If the cause is minor, such as irritation from litter dust or air fresheners, here are some things you can do:
- Switch to unscented, low-dust litter
- Avoid smoking or spraying perfumes around your cat
- Consider using a humidifier to add moisture to the air, which can help keep your cat’s nasal passages comfortable—particularly in dry or air-conditioned spaces.
- Wipe discharge from the nose or eyes with a clean, damp cloth
- Provide a warm, quiet space for rest and recovery
Constantly monitor your cat for worsening symptoms and consult your vet if you’re unsure.
Can Sneezing Be Prevented?
You can't prevent every sneeze, but here are some tips to reduce the risk of respiratory issues:
- Keep vaccinations up to date (especially for kittens and multi-cat households)
- Maintain a clean, dust-free living space
- Practice good litter box hygiene
- Feed a healthy diet to boost the immune system
- Minimize contact with other cats who may be sick
Final Thoughts
Occasional sneezing in cats is regular and usually nothing to worry about. But if it's happening regularly or is accompanied by other symptoms, it’s time to take a closer look. Whether the cause is a mild irritant or a more serious health issue, paying attention to your cat’s behavior and acting early can make all the difference.
If you're unsure, it's best to reach out to your veterinarian, who can provide guidance tailored to your cat’s individual health needs.
