How can I help my 7 year old cat stop sneezing and blowing out mucus.

Hi Carole,

A supplement like the NaturVet Hemp Allergy Aid is designed more for supporting skin and coat health and itchy skin vs. upper respiratory type symptoms. For upper respiratory signs truly caused by allergy, Zyrtec (cetirizine) may be helpful. You can read further with our article Zyrtec for Cats. If the nasal discharge is clear and occasional, a humidifier at night may also help. Alternatively, you can bring him into the bathroom during shower time and the steam can help loosen the nasal discharge. If you are seeing any kind of discolored discharge (yellow, green, white, etc.) an infection may be present, and you would really need to have a veterinarian assess whether antibiotics or another treatment may be indicated.
