Why is my 7-month-old indoor cat sneezing but has no other symptoms?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | unspayed | 5.5 lbs

My cat is about 7-month old now but she keeps sneezing these days. She has no fever or other problems. Also, she got all vaccines as an insider cat. Could you give me some thoughts on this? or should I visit Petco on Saturday?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Bunny. Sounds like she is suffering from a mild upper respiratory infection. Not sure how old she is but both kittens and adult cats suffer from these infections. Kittens get infected from their mothers who start shedding the viruses thus infecting the kittens. Many cats live their whole lives carrying these viruses. They will occasionally develop signs of upper respiratory infections during times of stress at any point in time. We vaccinate for a few of these upper respiratory viruses but we still see many many cases. The vaccines should provide some protection and usually adult cats develop very mild signs. Signs range from sneezing, runny eyes, runny nose, coughing, fever, lethargy, decreased appetite, decreased water intake, etc. Treating these infections can range from very simple to very complex cases that take weeks to months to improve. If signs remain mild, monitoring is sometimes appropriate. If the signs progress to not eating, lethargic, thick discharge from the nose and/or eyes, then you should get her evaluated by your veterinarian. They can gather a history, perform an exam, and advise you on possible diagnostics and treatment. Treatment can involve antibiotics to protect or treat secondary bacterial infections, antiviral medicines, a good deworming program, and vaccination program, eye drops/eye ointments if the eyes are involved, nose drops, a nutritional supplement called L-lysine added to his food may help, and probiotics are all things to try. Sometimes kittens have a nasopharyngeal polyp which can present as chronic upper respiratory disease which doesn't respond well to treatment. This is a polyp in the nasal passageway and back of the throat. These can be found by using sedation/anesthesia and evaluating the back of the throat and thus removed if found. Good luck.
