Cat ear mites can cause tear stains. Ear mites live in cats' ear canals and cause itchy ears and the production of large amounts of earwax. Because the facial nerves are connected, when a cat’s ears are itchy, the nerves in the nose and eyes will be stimulated, causing runny nose and tears. Over time, tear stains will appear. When suffering from ear mites, cats will constantly scratch their ears with their claws. The cat's face has auditory nerves and facial nerves interlaced with each other and is very sensitive. Pain deep in the ear canal will extend to around the eyes.

Solutions to cat ear mites:

1. When a cat is infected with ear mites, in order to prevent them from coming into contact with each other, it is recommended that the owner prepare a separate ear mite for the affected cat. Cage, lock it in for isolation and treatment to avoid possible contagion.

2. Next, start cleaning the cat’s ears. First, open the cat’s ears with one hand to expose the ear canal. Use the other hand to drop ear oil on a cotton ball and wipe it carefully, gently along the ear canal. Gently wipe away the dirt. If the cotton ball becomes dirty, replace it with a clean one.

3. After cat ear mites are completely cured, the cat may still relapse due to parasite infection, so the cat must be dewormed on time. Always keep ear cleaning liquid at home, clean the cat's earwax regularly, keep the ears clean, and pay attention to cleaning the inner ear canal.
