# Why Is My Cat Sneezing?


## Key Takeaways

- Sneezing in cats can stem from diverse etiologies including viral upper respiratory infections (URIs), environmental irritants (dust, smoke, perfumes, litter), dental disease impacting nasal passages, foreign body aspiration, and chronic inflammatory conditions.
- Home management should focus on environmental control by removing potential irritants and ensuring a calm, low-stress environment, alongside close monitoring of general health parameters like appetite, hydration, elimination, and activity levels.
- Immediate veterinary attention is warranted for emergent signs such as dyspnea, collapse, seizures, severe weakness, uncontrolled vomiting or diarrhea, obvious pain, inability to ambulate, or significant changes in vital functions, particularly in vulnerable populations like kittens, seniors, or immunocompromised individuals.
- Veterinary diagnostics will involve a thorough history and physical examination, potentially followed by laboratory tests (e.g., PCR for viral pathogens, complete blood count, serum chemistry), urinalysis, fecal analysis, and imaging modalities like radiography or CT scans to elucidate the underlying cause.
- Proactive risk reduction involves minimizing exposure to known irritants and prompt veterinary consultation for any persistent, severe, or worsening sneezing, especially when accompanied by other clinical signs such as ocular discharge, anorexia, or respiratory distress.

**Sneezing in a cat can be mild or serious depending on the pattern, timing, and other signs. It may involve local irritation, discomfort, stress, injury, stomach upset, skin changes, or another medical problem. Call your veterinarian when signs are persistent, severe, or worsening.**

## What symptoms or causes should I watch for?

- **Viral infection:** Upper respiratory infections are common in cats.
- **Irritants:** Dust, smoke, perfume, and litter can trigger sneezing.
- **Dental disease:** Some dental problems affect the nose.
- **Foreign material:** Grass or debris can irritate the nasal passages.
- **Chronic inflammation:** Some cats have recurring nasal disease.

## What can I safely do at home right now?

- **Keep your pet calm:** Use a quiet room and limit rough activity until you know what is happening.
- **Check the basics:** Look for appetite changes, water intake, bathroom habits, breathing, pain, and energy level.
- **Remove obvious risks:** Pick up unsafe food, plants, medication, trash, string, toys, or chemicals.
- **Record details:** Write down when it started, how often it happens, and what changed recently.
- **Call your vet:** A cat owner should ask for guidance if the sign continues or the pet seems unwell.

## When is this an emergency?

Go to an emergency veterinary clinic now if you notice:

- Trouble breathing, collapse, seizures, or severe weakness.
- Repeated vomiting, severe diarrhea, blood, or a swollen belly.
- Obvious pain, inability to walk normally, or crying when touched.
- Not eating, not drinking, or not urinating normally.
- Any rapidly worsening sign, especially in a puppy, kitten, senior pet, or chronically ill pet.

## What will my veterinarian check?

Your veterinarian will use the history and physical exam to narrow the cause. They may recommend lab work, urine testing, stool testing, imaging, skin or ear tests, or other diagnostics based on the sign.

## How can I reduce the risk next time?

Reduce irritants and call your vet for discharge, appetite loss, eye signs, or breathing trouble.
