How does a cat get conjunctivitis? - briefly
A cat can develop conjunctivitis due to bacterial or viral infections, allergies, foreign objects in the eye, or exposure to irritants like dust or chemicals.
How does a cat get conjunctivitis? - in detail
Conjunctivitis in cats, an inflammation of the conjunctiva—the thin membrane covering the inner surface of the eyelids and the white part of the eye—can arise from various causes. One primary cause is bacterial or viral infections. Feline herpesvirus, a common pathogen in cats, often leads to conjunctivitis, causing redness, swelling, and discharge. Bacterial infections, such as those caused by Chlamydia felis or Mycoplasma, can also trigger the condition, particularly in multi-cat environments or shelters where close contact facilitates the spread of pathogens. Environmental irritants, such as dust, smoke, or chemical fumes, can inflame the conjunctiva, leading to irritation and discomfort. Allergies, whether to pollen, mold, or certain foods, may also result in conjunctivitis as the immune system reacts to perceived threats. Physical trauma, such as scratches or foreign objects in the eye, can damage the conjunctiva, creating an entry point for infection or causing direct inflammation. Additionally, underlying health issues, like dry eye (keratoconjunctivitis sicca) or autoimmune diseases, can predispose cats to conjunctivitis by compromising the eye’s natural defenses. Poor hygiene or unsanitary living conditions can exacerbate the risk, as bacteria and other pathogens thrive in such environments. Early detection and treatment are crucial, as untreated conjunctivitis can lead to complications, including corneal ulcers or chronic eye problems. Regular veterinary check-ups and maintaining a clean, safe environment for the cat can help prevent this condition.
