It is said that the eyes are the windows to the soul. You can understand someone's full emotions, their thoughts, and their personality through one pair of eyes. A pair of eyes can convey so many things. Even the secretions of the eyes can tell us whether they are healthy or not...

Why cats and dogs cry:

The behavior of cats secreting tears is called epiphora in medical terminology, which means there are too many tears or the tears are overflowing. If not cleaned up in time, they will become tear stains. However, the behavior of epiphora itself does not pose a threat to the health of cats and dogs, mainly because the cause of epiphora is extremely important.

·Teething

When cats (4-7 months old) and dogs (3-6 months old) are changing teeth, various organs and structures in the head are developing, and their speed will suddenly put pressure on the tear ducts.

Note: Cats and dogs will bite some things and grind their claws (cats) to relieve the stress of the teething stage.

· Food

Reactions with additives in food, as well as excessive mineral content in water sources, can lead to excessive tears.

· Ear infection

Since the facial nerve intersects the auditory and facial nerves, when the ear canal is infected by bacteria, viruses, or parasites (or the ear is swollen or painful), the pain deep in the ear canal will extend to around the eyes.

·Special varieties

Flat-faced cats (such as Persians, chinchillas, fattened cats, etc.) and short-nosed dogs (mynas, French bulldogs, etc.) have large curvatures in their nasolacrimal ducts and limited fluid discharge. Even normal secretion cannot bear the burden.

· Eye infection/inflammation

In addition to the fluid, there will be a thick white/yellow discharge around the eyes.

· Tear duct abnormality/blockage

Fluid usually drains from the nose and is drained from the eyes when the tear ducts become blocked.

· Eye irritation

Dirt, foreign matter, allergies, and foreign matter will stimulate cats and dogs to flush them with tears; if the tears continue for more than 2 days, please rush to the hospital for examination immediately.

· Upper respiratory tract diseases

In addition to tears, complications such as sneezing, fever, runny nose, and drooling may occur.

· Conjunctivitis (pink eye)

Mainly caused by infectious respiratoryViral conjunctivitis caused by systemic diseases, the conjunctival congestion, water, and secretions of the eyes increase, and are generally divided into acute and chronic conjunctivitis.

Note: Herpes virus, mycoplasma, chlamydia, blocked tear ducts and drug allergies can all cause conjunctivitis.

· Keratitis

Corneal inflammation/swelling usually caused by herpes viruses; but less commonly, fungi, bacteria, allergies, and dry eyes can also cause keratitis.

· Corneal ulcer

There are scratches on the surface of the eyeball, but the cat or dog did not bother to scratch the eyeball when playing or scratching its ears.

· Excessively long hair/abnormal structure

Excessively long hair around the eyes or structural abnormalities of the eyelashes and eyelids (esotropia, exotropia) will cause constant friction against the cornea of ​​the eye.

In addition to the above reasons, there are other eye diseases that can also cause cats and dogs to secrete tears. Although this breaks your new discovery of emotional communication between cats and dogs, it does not mean that they are "emotionless killers". They are more restrained in their way of communication and require parents to be patient and observe. As long as you understand it, you will find that your feelings will heat up quickly~

NOTE: Cats who have difficulty producing tears are often diagnosed with dry eye and require eye drops to keep their eyes lubricated and stimulate tear production.
