Why Is My Cat Sneezing? Causes, Home Care, and When to See a Vet (2026 Guide)
An occasional sneeze from your cat is typically harmless—much like humans, cats sneeze to clear their nasal passages. However, frequent sneezing or sneezing accompanied by other symptoms can signal an underlying health issue requiring professional attention. This comprehensive guide explores the common causes of cat sneezing, safe home remedies for mild cases, and the critical warning signs that necessitate a veterinary visit.
Understanding Cat Sneezing: Normal vs. Concerning
Occasional Sneezing (Usually Normal)
Frequency: Once or twice a day.
Other Symptoms: None; the cat appears otherwise healthy and active.
Common Triggers: Dust, pollen, or a minor, transient irritant.
Frequent or Persistent Sneezing (Potentially Concerning)
Frequency: Multiple times per hour or in clusters (several sneezes in a row).
Duration: Persists for several days without improvement.
Accompanying Symptoms: Often seen with nasal/eye discharge, lethargy, or loss of appetite.
Common Causes of Sneezing in Cats
1. Upper Respiratory Infections (URIs)

The most prevalent cause of sneezing in cats.
Primary Causes: Feline herpesvirus (FHV-1) and feline calicivirus (FCV).
Treatment: Surgical removal for polyps; tumors require biopsy and a tailored treatment plan (surgery, radiation, chemotherapy).
7. Fungal Infections
Rare but serious conditions like cryptococcosis.
Symptoms: Chronic sneezing, thick nasal discharge, swelling of the nose or face, and in advanced cases, neurological signs.
Treatment: Long-term antifungal medications and sometimes surgery.
Safe Home Care for Mild Sneezing
Only attempt home care if your cat:
Sneezes occasionally.
Has no other symptoms (normal appetite, energy, and breathing).
Is eating and drinking normally.
Helpful Home Remedies
Increase Humidity: Use a humidifier or bring your cat into a steamy bathroom for 10-15 minutes to soothe nasal passages.
Saline Nasal Drops: Apply 2-3 drops of plain pediatric saline solution into each nostril 2-3 times daily to loosen mucus. Never use medicated human drops.
Support Nutrition & Hydration: Warm wet food to enhance aroma, offer low-sodium broth, and ensure fresh water is always available.
Provide Rest: Create a quiet, warm, and comfortable space for your cat to recover. Consider isolating them from other pets in a multi-cat household.
When to See a Veterinarian: Warning Signs
Seek Emergency Care Immediately
Difficulty breathing or open-mouth breathing.
Blue-tinged gums or tongue (indicating lack of oxygen).
Collapse or extreme lethargy.
High fever (over 103°F / 39.4°C).
Refusal to eat or drink for over 24 hours.
Schedule an Urgent Appointment (Within 24 Hours)
Frequent sneezing fits.
Colored (yellow, green) or bloody nasal discharge.
Eye discharge or swelling.
Lethargy, fever, or loss of appetite.
Schedule a Routine Check-up
Sneezing that persists for more than a few days.
Intermittent sneezing with mild discharge.
What to Expect at the Vet
Your veterinarian will perform a thorough physical exam and may recommend diagnostic tests such as:
Nasal Swab: To identify viral or bacterial causes.
Blood Work: To assess overall health and immune status.
Dental X-rays or Skull Radiographs: To check for dental disease, polyps, or tumors.
Rhinoscopy: Using a small camera to examine the nasal passages.
Biopsy: If a tumor is suspected.
Treatment and Prevention Strategies
Common Veterinary Treatments
Antibiotics: For secondary bacterial infections (e.g., Clavamox, Doxycycline).
Antivirals: For severe feline herpesvirus outbreaks (e.g., Famciclovir).
Supportive Care: Fluids for dehydration, appetite stimulants, and eye medications.
Prevention and Long-Term Management
Vaccination: Keep your cat up-to-date on the FVRCP vaccine, which protects against major viral causes of URIs.
Stress Reduction: Minimize environmental stress, as it can trigger herpesvirus flare-ups. Use pheromone diffusers (Feliway) and provide secure hiding spots.
Environmental Control: Use HEPA air purifiers, choose low-dust litter, avoid smoking indoors, and refrain from using strong aerosols or essential oils around your cat.
Regular Veterinary Care: Annual check-ups and proactive dental care are crucial for early detection and prevention.
Special Considerations
Kittens: Are highly vulnerable to severe URIs; seek prompt veterinary care for any sneezing.
Senior Cats: More prone to chronic conditions like dental disease and tumors; require closer monitoring.
Brachycephalic Breeds: Persians, Himalayans, and other flat-faced cats have narrower nasal passages and may experience more severe respiratory symptoms.
Conclusion
While an occasional sneeze is normal, persistent or severe sneezing is your cat's way of signaling that something is wrong. Monitoring your cat's overall behavior—their appetite, energy level, and breathing—is key. When in doubt, always consult your veterinarian. Early intervention can resolve minor issues and prevent them from developing into serious health problems.
For cats with chronic conditions like feline herpesvirus, lifelong management through stress reduction, good nutrition, and regular vet partnership can ensure a high quality of life.
