If a cat's eyes are tearing and cannot be opened, first of all, we must consider whether it is trauma, foreign bodies, trichiasis and other non-infectious factors. Remove the cause and use pet anti-inflammatory eye drops to slowly restore the cat to health. Secondly, we must consider viruses and bacteria. and parasitic infections, causing conjunctivitis. In this case, in addition to eye drops, antibiotics and drugs targeting the cause must also be used

1. Non-infectious factors

Trauma, entry of foreign bodies, and trichiasis irritation are all non-infectious factors that can irritate the cat’s eyes, causing tears and inability to open the eyes. In this case, it is first necessary to remove the cause of the disease, that is, remove impurities, foreign bodies, eyelashes, etc. that have entered the eyes so that the eyes are no longer irritated. Second, use professional anti-inflammatory eye drops for pets. In the first few days, you need to maintain a relatively high frequency of eye drops, 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 and swelling, tearing, swelling of the eyelids, and the inability to open. In severe cases, the cornea may even be inflammation, corneal ulcer, corneal necrosis, and finally blindness. For example, "cat nasal congestion" is a common and highly contagious disease in cats, which can cause unilateral or bilateral conjunctivitis, accompanied by respiratory symptoms: elevated body temperature, sneezing, purulent nasal discharge, etc. Owners can take their cats to the hospital for a PCR test to check whether they are infected with viruses or bacteria. After diagnosis, they can use corresponding antibiotics and eye drops. Some cats are not properly dewormed and may be infected with eye nematodes, which may cause the cat's conjunctiva to become red and swollen, making it difficult to open the eyes and causing tears. In the later stages of development, the owner can even see the "surging" of nematodes in the conjunctival sac with the naked eye, and the cat needs to be taken to a pet hospital for surgical treatment in time.
