Sneezing and nasal discharge in cats
Occasional sneezing may be minor, but repeated sneezing with nasal discharge can accompany infection, irritation, dental disease, a foreign body or another condition. Appetite and breathing determine urgency.

✓ Note whether discharge is one-sided
✓ Blocked noses can reduce appetite
✓ Eye pain or breathing difficulty needs prompt care
✓ Human cold remedies are unsafe
An occasional sneeze can follow dust or a strong smell. Repeated sneezing, discharge or reduced appetite may reflect infection, inflammation, dental disease or a foreign object and deserves attention.
Describe the pattern clearly
Note frequency, duration and whether one or both nostrils are affected. Describe discharge as clear, cloudy, yellow, green or bloody and record eye changes, face rubbing, swelling, recent dental signs, new cats and exposure to dust or fragrance.
Support comfort without medicating
Gently wipe only the outside of the nose with clean damp material, provide fresh water and offer familiar complete food at a comfortable temperature. Keep the cat indoors and reduce airborne fragrance. Do not use steam close to the face or force food.
Avoid human cold remedies
Do not give decongestants, antihistamines, pain medicine, essential oils, nasal sprays or leftover antibiotics unless a veterinarian has prescribed the exact product and dose. Never insert cotton buds or instruments into a nostril.
Protect appetite and vulnerable cats
Cats rely on smell when eating, so congestion may reduce intake. Measure what is actually eaten and seek prompt advice for kittens, seniors, medically vulnerable cats or any cat with lethargy, fever-like illness, facial swelling, blood or reduced eating.
Escalate breathing changes
Open-mouth breathing, marked effort, abnormal gum colour, collapse or inability to rest is an emergency. Persistent or recurring discharge also needs examination even when breathing remains comfortable, especially when only one nostril is involved.

Repeated litter-box straining may be constipation or a urinary emergency. If normal urine cannot be confirmed—especially in a male cat—contact an emergency veterinarian immediately and do not wait to identify the cause at home.
