Expert Answer

Persistent black nasal discharge in a cat may be a secondary symptom of ear mite infection, or it may be caused by ‘internal heat’ or feline rhinotracheitis. Check the cat’s ears for dirt or odor; if none, you can rule out ear mite infection.

Feline rhinotracheitis signs include conjunctivitis, increased eye discharge, sneezing, and runny nose; severe cases show drooling, lethargy, poor appetite, fever, and coughing. The owner can combine the cat’s symptoms and situation to find the cause. If symptoms worsen or others appear, promptly take the cat to a vet.
