Owners should pay attention to the discharge of pus from the kitten's eyes. This is a symptom of virus infection in the kitten's eyes. It may be conjunctivitis, feline nasal congestion, or the production of herpes virus. It is recommended that the owner first determine the kitten's condition before proceeding. Purchase medicine for targeted treatment, and during this period, the cat should be supplemented with lysine and catamine, which can make the kitten's eyes heal faster and avoid worsening of the condition.
