✓ 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 discharge
Record clear, cloudy, yellow, green or bloody discharge and whether it comes from one or both nostrils. Note eye discharge, noisy breathing and facial swelling.
Support comfort
Offer familiar aromatic wet food, fresh water and a calm warm room. Gently wipe the nose with a damp soft pad. Do not use essential oils, vapor rubs or human decongestants.
Limit spread
If several cats live together, use separate bowls and wash hands while seeking veterinary advice. Some respiratory infections spread readily between cats.
Arrange care
Call for persistent signs, reduced food intake, lethargy, blood, one-sided discharge or recurrence. Open-mouth breathing or severe effort is an emergency.

A clear increase in thirst is worth measuring and discussing with a veterinarian. Never restrict water while you investigate the cause.
