Dehydration
* A dry nose and eyes can be a sign of dehydration, which can be caused by several factors such as not drinking enough water, illness, or excessive heat.
Respiratory Infection
* A dry nose and brown gunk around the eyes can also be symptoms of a respiratory infection, such as feline upper respiratory infection (URI).
Allergic Reaction
* Allergies to food or environmental allergens such as dust or pollen can cause a runny nose, itchy eyes, and other symptoms.
Eye Infection
* Conjunctivitis or other eye infections can cause brown discharge around the eyes and may be accompanied by squinting, pawing at the eyes, and sensitivity to light.
Dental Disease
* Dental problems, such as gingivitis or tooth decay, can cause a brown discharge from the nose and eyes due to inflammation and infection.
Liver or Kidney Disease
* Brown discharge around the eyes can be a sign of liver or kidney issues, as toxins can build up in the body and affect the skin and mucous membranes.
Trauma or Injury
* Injury to the nose or eye area could also lead to a dry nose, discharge, and other symptoms.
It's important for a veterinarian to examine your cat, assess its overall health, and perform tests to determine the underlying cause of the symptoms. Treatment will depend on the specific diagnosis and may include antibiotics, antihistamines, eye drops or ointments, or other medications as appropriate.
