Why is my cat sneezing so much?

Most sneezing in cats comes from upper respiratory infections (cat flu), which are common in kittens and shelter cats. Dust, strong scents and something stuck in the nose are other causes.

Home care: keep the cat warm, wipe the nose and eyes, and offer smelly wet food, since cats who can't smell often stop eating.

See a vet if: there's thick yellow or green discharge, sneezing lasts over a week, your cat stops eating for 24 hours, or breathes with an open mouth.
