Cat tears can be treated with sterilizing and anti-inflammatory eye drops, such as Taiqu Cat Eye Drops. You can also use chloramphenicol eye ointment, erythromycin eye ointment, chlortetracycline eye ointment, etc. Cat's tears may be caused by internal heat, nasal congestion or other eye diseases. Before applying eye drops, it is best to clean the cat's lower eyes with physiological saline, which can have a sterilizing effect, and then instill eye drops on time. That’s it. If the situation is serious, it’s best to go to the hospital for examination. Tears caused by nasal branch in cats need to be treated in time, otherwise tear marks will easily remain.
