Cats' Excessive Tears: Common Causes and Solutions
Reasons Why Cats Cry Tears:
1. Inflammation of the Nasal and Eyelid Area
When a cat's eyes become inflamed, they can feel sore and dry, prompting them to involuntarily shed tears. If you notice your cat's eye area is red, it might indicate an inflammation that requires attention.
2. Obstruction of the Nasolacrimal Duct
Under normal circumstances, tears flow through the tear ducts into the nose. However, if the ducts are blocked, tears can accumulate around the eyes and overflow from the lower eyelids, giving the appearance of excessive tears in your cat's eyes.
3. Foreign Objects, Hair, or Eyelashes Irritating the Eyes
If a foreign object, hair, or eyelashes enter a cat's eye, it can cause irritation and excessive tearing as the tears help to wash away the irritant. Some cats may also have "inverted eyelashes," where the lashes grow inward and continuously irritate the eye, leading to excessive tearing.
4. Irritants Such as Gases or Foods
Cats have delicate eyes, and exposure to irritants like strong gases can stimulate the tear glands, causing tears to flow. Additionally, if a cat's diet contains too much salt, it can increase tear production, resulting in excessive tears.
5. Certain Infectious Diseases
Conditions such as feline herpesvirus, calicivirus, mycoplasma, and chlamydia can lead to excessive tearing, often accompanied by symptoms like conjunctivitis and keratitis. These infections can cause your cat to continually shed tears.
6. Ear Inflammation and Constant Scratching
Cats have a rich network of nerves in their face, and the pain from scratching an inflamed ear can stimulate tear production. If the tears cannot exit through the nasolacrimal ducts, they may溢出 from the corners of the eyes.
Tip: There are many reasons why cats might cry tears. If you notice your feline friend is excessively wateryeyed, it's crucial to take them to the vet immediately for a checkup and treatment. Always consult with a professional veterinarian for advice.
