Sneezing in cats can occur for various reasons. Its significance depends on the frequency of occurrence. If it happens occasionally, it is less concerning. However, it becomes significant if it is persistent. Below are the most common causes:

Mild or Environmental Causes

• Irritants in the environment: Dust, smoke, perfumes, cleaning sprays, strong odors, or litter dust can all trigger sneezing.
• Seasonal allergies: Though less common in cats than in humans, allergies may occasionally contribute.

Medical Causes

• Upper Respiratory Infections (URI): The most frequent cause, often linked to viruses such as feline herpesvirus (FHV-1) or calicivirus. These infections are typically accompanied by watery or discolored nasal discharge, eye discharge, lethargy, or reduced appetite.
• Bacterial infections: Secondary infections (e.g., Bordetella, Chlamydia) may develop following a viral illness.
• Dental disease: Infections of the teeth or gums—particularly in the upper jaw—can extend into the nasal passages, causing sneezing.
• Nasal conditions: Polyps, tumors, or foreign objects (such as grass blades) within the nasal cavity may lead to chronic or recurrent sneezing.

When to Seek Veterinary Attention

You should consult a veterinarian if:

• Sneezing is frequent, persistent, or worsening.
• Nasal discharge is present (clear, yellow, green, or bloody).
• Additional symptoms appear, such as eye discharge, poor appetite, lethargy, or difficulty breathing.
• The cat sneezes blood (epistaxis), which requires urgent care.

Recommended Actions

• For mild and occasional sneezing, monitor your cat and reduce environmental irritants (e.g., switch to dust-free litter, avoid using sprays or strong-smelling products).
• For frequent sneezing, nasal discharge, or signs of illness, seek veterinary care promptly. Diagnostic testing and appropriate treatment—such as antibiotics, antivirals, or supportive care—may be required.
