Understand Feline Nasal Disorders
Sniffles or a runny nose that last for more than about ten days warrant a call for veterinary attention because they can signify viral or bacterial infection.
Every so often, one of your cats comes down with a bout of the “sniffles.” In most cases, you have nothing to worry about. The sneezing and runny nose should simply fade away within a few days. But if the signs persist for longer than that — especially if the cat is not eating and not behaving normally, or the discharge from her nose thickens and becomes darker in color — a visit to your veterinarian is in order.
