Common Causes of Cat's Persistent Eye Discharge: What's

The Origin of Cat's Tear Stains

Have you ever wondered why cats develop those unsightly tear stains? It's often due to an overproduction of tears that, left unchecked, can lead to bacterial growth and the accumulation of a substance called porphyrin. When this porphyrin oxidizes upon contact with air, it turns into a rustlike color, creating those deep, persistent stains. The primary reason for these stains is the chronic abnormal discharge of tears. But why does this happen? Here are some common reasons:

1. Malformed Nasolacrimal Ducts

Shortnosed and flatfaced cats, with their unique facial structures, are prone to tear stains. The bent nasolacrimal ducts in flatfaced cats can cause tears to stagnate as they pass through, leading to overflow and, over time, the formation of tear stains.

Solutions:

Regular eye care is essential for these cats. Gently wipe away any tears and consider using petspecific tear stain removers. Be gentle to avoid damaging the skin.

2. Eye Diseases

Eye conditions like conjunctivitis or keratitis, often caused by infections, can lead to excessive tear production and the presence of sticky or puslike discharge, making tear stains more stubborn.

Solutions:

Seek veterinary care promptly. Follow the vet's advice for treatment, which may include antibacterial or antiviral eye drops.

3. Entropion or Ectropion

Entropion is when eyelashes grow inward, irritating the eye and causing excessive tearing. Ectropion, on the other hand, is when the eyelids roll outward, exposing the eye to irritants and leading to similar issues.

Solutions:

Surgical correction is typically required for these conditions.

4. Obstructed Nasolacrimal Ducts

Blockages in the nasolacrimal ducts can be caused by foreign particles like dust, preventing tears from draining properly and leading to overflow and tear stains.

Solutions:

Under veterinary guidance, a duct flushing procedure may be necessary to clear the blockage.

5. Parasite Infections

Parasites like hookworms can irritate the eyes, causing excessive tearing and the development of tear stains.

Solutions:

Immediate veterinary treatment is needed to remove the parasites. Regular deworming and maintaining a clean environment are crucial to prevent reinfection.

6. Ear Infections

Ear mites and other ear infections can stimulate the tear glands, leading to excessive tear production and tear stains.

Solutions:

Treat the ear infection promptly to prevent further irritation.

7. Poor Diet

A diet high in salt and fat can lead to excess salt and fat being secreted through the tear glands, causing dark stains. A deficiency in trace elements can also make the eyes sensitive and itchy, leading to more tearing.

Solutions:

Adjust your cat's diet to be more balanced and nutritious, ensuring they receive adequate vitamins and minerals.

In summary, understanding the various causes of tear stains can help you take the necessary steps to keep your feline friend's face looking clean and healthy.
