Why does my cat sneeze mucus from one nostril? Is it allergies?

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear that your cats are having issues with sneezing. Sneezing in cats can have a variety of causes, such as allergies or an underlying upper respiratory infection. As Annie is having nasal discharge now with her sneezing, I would recommend she be evaluated by her regular veterinarian, as she may have an infection or some other underlying condition that would need to be treated in order to resolve it. Good luck!

This may be from an allergy or a sinus or upper respiratory infection. It is common in cats and quickly can progress to a decreased appetite and lethargy. Most respiratory infections in cats are from viral infections that can be contagious to other cats. If he is eating still, then you can make an appointment with your vet and do no need to get him treated as an emergency

Thank you for submitting your question regarding Mickey. Cats can develop allergies that result in respiratory symptoms. However, with his history of coming from a shelter, it is more likely that he has an upper respiratory tract infection. If his symptoms persist, he will need to see a veterinarian as he may require a medication. In the meantime, encourage him to eat and drink. I hope this information helps and congratulations on your new cat!

She is probably suffering from a chronic upper respiratory infection, you need to take her to the vet to get it checked and treated, a relatively long course of antibiotic will likely be needed to treat this condition.

Poor Sneakers! If she is having persistent sneezing and nasal discharge even after treatment with antibiotics, and you are also seeing a bump of some kind inside her nostril, I would be concerned that she may have a nasal tumor or foreign body of some kind in her nose. If your veterinarian does not have any suggestions for further work-up at this point, I would recommend asking for referral to a specialist for rhinoscopy (looking at the inside of the nasal cavity with a small camera), as well as other testing if needed such as a bacterial or fungal culture, biopsy of the lump, etc. to try and get a diagnosis.

It's probably an upper respiratory infection, it could also be a polip in the nasal cavity that is causing this. you shouldn't put anything topically on his nose as he will lick it instantly. you will need to take Charlie to the vet in order to get it checked ASAP.

If she is young or is undergoing a lot of stress (moving, new animal or person in the house, change of schedule) the most likely cause is a viral upper respiratory infection. Many cats will get by with the following support - lysine supplement- try Vetoquinol Viralys (L-Lysine) Oral Gel for Cats - treat all cats as directed on the bottle until all cats are well - try wet food or soaking kibbles and then very slightly warming the food. Cats are very smell-driven and warm wet food is smellier and more likely to be eaten by a stuffy nosed cat. - recommend a probiotic such as purina Fortiflora for every cat in the home. Odd as it sounds, we’ve found that probiotics actually speed recovery from URI’s - if any cat is squinting an eye or thick eye discharge, refuses to eat, or becomes lethargic, it’s time to see your vet. These are signs of eye ulcers and/or secondary bacterial infection. These cats will need eye ointments or systemic antibiotics. Occasionally, nebulizations or more aggressive treatment is needed. If Mama is lethargic, has decreased appetite, or the nasal discharge is thick, yellow/green, or bloody, or she is breathing with her mouth open, she needs to see the vet as these could be something more serious such as fungal infection, cancer, or secondary infection. Best of luck to you and Mama.
