A cat's eyes that suddenly cannot open and shed tears may be caused by internal heat, feline herpes virus, foreign body irritation, or conjunctivitis. It is best to take the cat to the pet hospital for examination to confirm the specific cause. Carry out targeted treatment to avoid delaying the condition.
Tips:
Usually pay attention to the cat’s diet and eye hygiene, and do not feed the cat too salty food. If there are any foreign objects in the body, they should be cleaned immediately to avoid bacterial infection.
