Cats will cry when they are frightened, uncomfortable, etc. The discharge from the eyes of cats that we usually see is not the cat’s tears, but caused by improper diet or other diseases. Most of the time, the discharge from the cat’s eyes is not the cat’s tears. Emotions will be expressed through barks. Owners should pay attention to the cat's condition, pay attention to and comfort the cat's emotions in a timely manner, and send the cat to the pet hospital for examination and treatment immediately if there is any abnormality in the cat's body to avoid life danger.
