✓ 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.
Record pattern and discharge
Note whether one or both nostrils are affected and describe discharge as clear, cloudy, yellow, green or bloody. Track appetite, drinking, eye changes, breathing and exposure to dust, fragrance or other cats. Gently wipe the outside of the nose with a damp soft cloth, but do not insert cotton buds or apply human decongestants.
Escalate when breathing or eating changes
Contact a veterinarian promptly for persistent symptoms, blood, facial swelling, fever, lethargy, reduced eating or a kitten with discharge. Open-mouth breathing, marked effort or blue or pale gums is an emergency. Because cats rely on smell to eat, warming suitable food may help briefly, but appetite loss still needs timely professional advice.

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