Green mucous is a sign of infection. Poor Zena. She may be showing early signs of an upper respiratory infection (URI). If that is the case you may be able to stop things from getting too bad if you act early. Other possible causes are a fungal infection or parasite problem (not as common). Most cats URI's are initially caused by a viral infection that later on turns into a secondary bacterial infection. To help boost Zenas immune system you can give her over the counter Lysine (antiviral medicine) from your local pet store. Then visit your local vet to get her examined and treated (i.e. Antibiotics) if the green mucous continues or if Zena starts sneezing, coughing or having difficulty breathing. Hopefully this is a mild URI and nothing more.

    Green mucous in the nose is a sign of infection, it could also be due to a foreign body in the nasal cavity. you should take Zena to the vet in order to get it checked, if only an infection is suspected she will need an antibiotic course.
