1. Non-infectious factors

Trauma, foreign body entry, and inverse eyelash stimulation are all non-infectious factors, which stimulate the cat's eyes, causing tears and unable to open their eyes. In this case, the cause of the disease is first necessary, that is, the impurities of foreign objects, eyelashes, etc. entering the eyes, so that the eyes will no longer be irritated. Second, use professional pet anti-inflammatory eye drops. In the first few days, you need to maintain a relatively high eye drop frequency, 7-8 times a day, to relieve eye inflammation and moisten the eyes.

2. Infectious factors

Viruses, bacteria and parasites infect the eyes, causing inflammation of the conjunctiva, redness, tears, swelling of the eyelids, and inability to open them. They may develop severely, even keratitis, corneal ulcers, corneal necrosis, and finally, they are embarrassed. For example, "cat's nose brace" is a common highly contagious disease in cats, which can cause unilateral or bilateral conjunctivitis, accompanied by respiratory symptoms: increased body temperature, sneezing, purulent nasal discharge, etc. The owner can take the cat to the hospital for PCR test to check whether it is infected with viruses and bacteria. After diagnosis, use the corresponding antibiotic drug treatment with eye drops. Some cats do not do deworming properly, which may infect eye nematodes, which may stimulate cats' conjunctiva to redness, swollen eyes and unable to open their eyes and tears. In the later stages of development, the owner can even see nematodes in the conjunctival sac that are "surging" and the cat needs to be taken to the pet hospital for surgical treatment in time.
