Occasional sneezing in cats is normal, but frequent or constant sneezing can be a sign of an underlying problem. Understanding the cause helps you know when it’s harmless—and when it’s time to see a vet.

What You Can Do at Home

Steam can help relieve congestion.

Don’t use essential oils near cats

Don’t ignore symptoms lasting more than a few days
